Indoor Rowing

Indoor rowing (ergometer or "erg") is a full-body, low-impact cardiovascular exercise that emphasizes posterior chain development while combining aerobic conditioning with muscular endurance. The rowing stroke distributes effort across legs (approximately 60%), core (20%), and upper body (20%), making it one of the most comprehensive single exercises for total-body fitness. Unlike running, rowing is non-impact while still providing high calorie expenditure, making it particularly valuable for those with joint limitations or seeking balanced muscular development.

Muscles Trained

Primary Muscles

Role: Primary driver of the rowing stroke, providing the majority of power through knee extension during the drive phase

Activation Level: Very High (75-90% during drive phase)

Phase-Specific Notes:

  • Catch: Quadriceps are maximally lengthened with knees fully flexed
  • Drive: Peak activation occurs in first half of drive as knees extend powerfully
  • Finish: Minimal activation as knees reach full extension
  • Recovery: Eccentric loading as knees flex under control to return to catch

Training Implications: Rowing develops exceptional quadriceps muscular endurance. The sustained nature of rowing creates different adaptations than explosive movements like squats—emphasizing endurance over maximal strength. Athletes may have well-developed quads but still lack single-rep maximal strength.

Secondary Muscles

Role: Assist in hip extension during drive, eccentric control during recovery

Activation Level: Moderate (50-65%)

Function: While quadriceps dominate knee extension, hamstrings work synergistically with glutes for hip extension. The seated position and forward knee tracking pattern means hamstrings are less activated than in hip-hinge movements like deadlifts. They also provide important eccentric control as knees flex during the recovery phase.

Training Implications: Rowing provides moderate hamstring endurance but doesn't fully develop hamstring strength. Rowers often benefit from supplemental hamstring work (Romanian deadlifts, Nordic curls) to balance quad dominance.

Stabilizers

Muscle GroupRoleActivation Level
Posterior DeltoidsShoulder extension during pull, scapular stabilityModerate (40-60%)
Rotator CuffShoulder stabilization throughout stroke cycleModerate continuous (35-50%)
ObliquesPrevent trunk rotation, maintain centered positionModerate (40-55%)
Hip Flexors (Iliopsoas)Control hip flexion during recovery phaseLow to Moderate (30-45%)
Tibialis AnteriorDorsiflex ankle during recovery, control foot positionLow (25-40%)

Joints Involved

Demand Level: Very High - most active joint in rowing stroke

Primary Movements:

  • Flexion/Extension: Full range from approximately 130-160 degrees flexion (catch) to nearly full extension (0-10 degrees at finish)
  • Compression: Significant compressive forces during drive phase as body weight and pulling force load the joint

Mobility Requirements:

  • Good knee flexion (at least 130 degrees) for proper catch position
  • Full knee extension for effective drive completion
  • No valgus/varus deviation during drive

Common Issues:

  • Patellar tendinopathy: Overuse from repetitive knee extension under load
  • Iliotibial band friction: ITB tightness causing lateral knee pain with high volume
  • Improper tracking: Knees caving inward (valgus) indicates hip weakness
  • Incomplete extension: Limited quad strength or mobility restricts full drive

Training Implications: The seated position and forward knee travel creates different loading than squats. Good for those with running-related knee pain, as there's no impact. However, existing patellar tendinopathy may be aggravated by high-volume rowing.

Energy Systems

SPM = Strokes Per Minute

Note on Stroke Rate: Lower stroke rates (18-22) emphasize power per stroke with longer drive phases. Higher rates (28-36+) emphasize faster turnover and are typically used for racing and high-intensity intervals. Optimal racing rate for 2k is typically 32-36 SPM for most rowers.

Common Imbalances

What Rowing Overdevelops

Muscle/PatternSigns of OverdevelopmentWhy It Happens
Latissimus DorsiRounded shoulders, limited overhead reach, arms hang with palms facing backwardContinuous horizontal pulling throughout stroke cycle with high training volume
QuadricepsQuad dominance over hamstrings, anterior knee pain, tight rectus femorisKnee extension is primary power source, legs contribute 60% of stroke power
Scapular Protractors (Serratus Anterior)Shoulders round forward at rest, scapulae sit wide on ribcageArms reach forward thousands of times per session, emphasizing protraction
Hip FlexorsTight iliopsoas, anterior pelvic tilt, difficulty with hip extensionRepetitive hip flexion during recovery phase, seated position
Spinal Erectors (Lower Back)Chronically tight low back, excessive lumbar lordosisConstant isometric contraction to maintain posture, fatigue from sustained activation

What Rowing Undertrains

Muscle/PatternConsequencesWhy It's Neglected
Pectorals & Anterior DeltoidsWeakness in pushing movements, poor bench press strength relative to row strengthNo pushing component in rowing stroke, pure pulling motion
Scapular Retractors (Rhomboids, Middle Trap)Actually get good work—NOT undertrainedUnlike swimming, rowing emphasizes retraction at finish
HamstringsWeak relative to quads, limited hip hinge strength, potential imbalanceSecondary role to quads, seated position limits hamstring contribution
CalvesUnderdeveloped compared to quads, limited plantar flexion strengthMinimal calf involvement, foot is strapped to footplate
External RotatorsShoulder instability, reduced shoulder healthLimited rotational demand in rowing stroke

Postural Considerations

Common Postural Pattern: "Rower's Posture"

  • Forward shoulder position from lat and pec minor tightness
  • Strong but potentially short hip flexors
  • Well-developed but potentially fatigued spinal erectors
  • Strong scapular retractors (better than swimmers/cyclists)

Key Difference from Swimmers: Rowers typically have better scapular retractor strength due to the finish position requiring strong retraction. However, they still develop pulling dominance and forward shoulder position from lat overdevelopment.

Functional Impact:

  • Excellent pulling strength but poor pushing strength ratio (ideally, rowing strength should approximate bench press strength; rowers often row 2x what they can bench)
  • Strong legs but quad-dominant pattern
  • Good core endurance but potential for low back fatigue/strain
  • Generally good upright posture compared to cyclists but still rounded shoulders from pulling volume

Complementary Training

Priority Exercises

Purpose: Balance pulling dominance, prevent forward shoulder posture, develop chest and anterior shoulder strength

Essential Exercises:

  1. Horizontal Pressing (Primary Priority)

    • Bench Press (barbell or dumbbell): 3 sets of 6-10 reps, 2x per week
    • Push-ups: 3 sets of 10-20 reps, can be done daily
    • Dumbbell Chest Press: Allows independent arm movement, addresses asymmetries
  2. Vertical Pressing (Secondary Priority)

    • Overhead Press: 3 sets of 6-10 reps, develops shoulder strength in different plane
    • Landmine Press: Safer angle for those with shoulder issues
  3. Dip Variations

    • Parallel bar dips or bench dips for tricep and lower chest development

Programming Notes:

  • Aim for 2-3 pushing sessions per week
  • Volume should roughly match rowing volume (if you row 1 hour, spend 30-45 min on pushing work)
  • Ideal ratio: For every horizontal pull, do approximately 0.7-1.0 horizontal push
  • Focus on full range of motion, especially deep stretch at bottom of press

Expected Benefits:

  • Reduced forward shoulder posture
  • Better shoulder joint balance and stability
  • Improved bench press strength (though will always lag row strength somewhat)
  • Reduced risk of shoulder impingement

Warning Signs

Pay attention to these red flags that indicate potential injury development:

  1. Low Back Pain

    • Pain during or after rowing, especially in lumbar spine
    • Morning stiffness that improves with movement
    • Pain with bending forward or backward
    • Action: Check form (video yourself), reduce volume, strengthen core, see practitioner if persists over 1 week
  2. Rib Pain

    • Sharp pain along ribs, especially during breathing or catch position
    • Tenderness to touch along rib line
    • Pain that increases with training volume
    • Action: IMMEDIATE reduction in volume, medical evaluation (stress fracture concern), no rowing through rib pain
  3. Knee Pain

    • Pain during drive phase, especially around patella
    • Pain descending stairs or squatting
    • Swelling around kneecap
    • Action: Check footplate setup, evaluate knee tracking, reduce volume, quad/VMO strengthening
  4. Wrist Pain

    • Pain during or after rowing in wrist
    • Discomfort with gripping or daily activities
    • Pain with wrist flexion/extension
    • Action: Check grip (likely too tight), ensure neutral wrist, may need wrist support temporarily
  5. Anterior Shoulder Pain

    • Pain at catch position (arms extended forward)
    • Discomfort with reaching overhead
    • Clicking or catching sensation
    • Action: Check for early arm pull, strengthen scapular stabilizers, ensure proper sequencing
  6. Persistent Fatigue

    • Inability to maintain proper form late in pieces
    • Worsening splits despite consistent effort
    • Form breakdown (losing neutral spine, rushing slide)
    • Action: May indicate overtraining; reduce volume, ensure adequate recovery, nutrition, sleep

Prevention Strategies

  1. Master Proper Technique Early

    • Work with qualified coach or use video analysis
    • Focus on "legs, core, arms" on drive; reverse on recovery
    • Maintain neutral spine throughout stroke
    • Proper catch position without overreaching
    • Limit layback to 10-15 degrees past vertical
  2. Progress Volume Gradually

    • Follow 10% rule: don't increase weekly volume more than 10%
    • New rowers: start with 15-20 minute sessions
    • Build to longer steady-state before adding high-intensity intervals
    • Take at least 1-2 complete rest days per week
  3. Prioritize Core Strength

    • Strong core prevents low back injury (most common rowing injury)
    • Anti-extension exercises: planks, dead bugs, rollouts
    • Anti-rotation exercises: Pallof press, side planks
    • Anti-flexion: bird dogs, back extensions
    • Minimum 2-3 core sessions per week, 10-15 minutes
  4. Balance with Complementary Training

    • Pushing exercises to counter pulling dominance
    • Hip mobility to prevent flexor tightness
    • Hamstring work to balance quad development
    • Single-leg exercises for symmetry
    • See Complementary Training section for specifics
  5. Monitor and Adjust

    • Track metrics: splits, stroke rate, heart rate, perceived effort
    • Note any pain or discomfort immediately
    • Modify or skip sessions if pain is present
    • Use easy technique days for recovery
    • Film yourself monthly to catch form degradation
  6. Optimize Ergometer Setup

    • Footplate height: Ball of foot aligned with strap, heels can lift slightly at catch
    • Damper setting: 3-5 for most people (lower for technique, higher for power work)
    • Monitor height: Eye level when seated, about 1 meter away
    • Handle height at finish: Level with lower ribs/upper abdomen, elbows past body
  7. Warm Up and Cool Down

    • 5-10 minutes easy rowing before hard efforts
    • Start at low stroke rate (18-20 SPM) for first few minutes
    • Gradually increase intensity
    • Cool down with 5 minutes easy rowing
    • Post-rowing mobility work for hips and lats
  8. Listen to Your Body

    • Differentiate normal muscle fatigue from joint/tendon pain
    • Joint pain = take action, don't push through
    • Muscle soreness = normal, can work through
    • When in doubt, take an extra rest day
    • Seek professional evaluation for persistent issues

For Mo

When to Recommend Indoor Rowing:

  • Users seeking full-body cardio without impact stress
  • Those with running-related joint pain (knees, ankles, hips)
  • Athletes wanting to develop pulling strength alongside cardio
  • Rehabilitation from lower-body impact injuries
  • Cross-training for runners, cyclists, swimmers
  • General fitness population seeking efficient calorie burn
  • Users with good back health and proper form capacity

Who Benefits Most:

  • Former athletes looking for challenging conditioning
  • People with strong backs who can maintain neutral spine
  • Those willing to learn proper technique
  • Users seeking balanced muscle development
  • Athletes in sports requiring pulling strength (climbing, wrestling, swimming)
  • Individuals comfortable with structured interval training

Red Flags to Watch For:

  • Existing low back pain: Most common rowing injury; proceed cautiously with technique emphasis
  • Rib pain: Immediate cessation; potential stress fracture in competitive rowers
  • Poor hip mobility: Will compensate with lumbar flexion, increasing injury risk
  • Knee issues: Patellar tendinopathy may be aggravated; monitor volume carefully
  • Inability to maintain neutral spine: Core weakness or mobility limitations make rowing risky
  • Rushing recovery: Most common technical fault; leads to inefficiency and back strain
  • Death grip: Overgripping causes wrist and forearm issues

Technique Cues to Emphasize:

  1. Sequencing is everything: "Legs, core, arms" on drive; reverse on recovery
  2. Neutral spine always: No rounding at catch, limit layback to 10-15 degrees
  3. Controlled recovery: Slow slide forward (ratio ~1:2, drive:recovery)
  4. Legs initiate: Arms stay long until legs are extended
  5. Relaxed grip: Hook fingers, don't death-grip
  6. Straight wrists: Neutral wrist alignment throughout

Programming Guidance:

For Beginners:

  • Start: 3x15-20 min sessions per week at easy pace (65-75% max HR)
  • Focus: Perfect technique before adding intensity or volume
  • Stroke rate: 18-22 SPM for learning
  • Progress: Add 5 minutes per week until reaching 30-45 min continuous
  • After 4-6 weeks: Introduce basic intervals (e.g., 8x2 min at tempo, 1 min rest)

For Intermediate:

  • 4-5x per week, mix of steady-state (30-60 min) and intervals
  • One long session: 45-60 min at 70-80% max HR, 20-24 SPM
  • Two interval sessions: Various formats (8x500m, 4x2k, etc.)
  • One recovery session: 20-30 min easy
  • Complementary strength: 2x per week pushing/posterior chain work

For Advanced:

  • 5-6x per week with periodized training
  • Include all energy systems: long aerobic, threshold, VO2 max, anaerobic
  • Standard benchmarks: 2k test, 5k test, 30-min max distance
  • Competitive goals: 2k under 7:00 (men), 8:00 (women) = good club level
  • Heavy emphasis on complementary training to prevent imbalances

Integration with Other Activities:

  • Running: Excellent cross-training, reduces impact load while maintaining cardio
  • Cycling: Good complement, adds upper body and posterior chain work
  • Swimming: Both are pulling-dominant; ensure adequate pushing work to balance
  • Strength Training: Natural pairing; rowing is conditioning, weights for strength
  • Sports (climbing, martial arts, team sports): Good general conditioning tool

Common Mistakes to Coach Against:

  1. Pulling with arms too early: Kills efficiency, strains shoulders
  2. Rushing the slide: Recovery should be slower than drive
  3. Overreaching at catch: Causes lumbar flexion and low back strain
  4. Excessive layback: More than 15 degrees past vertical wastes energy, strains back
  5. Lifting shoulders/tensing: Creates neck tension, wastes energy
  6. Knees caving inward: Hip weakness, potential for knee pain
  7. Gripping too tight: Forearm fatigue, wrist issues
  8. Shooting the slide: Legs extend but body doesn't follow, then arms yank

Progressions and Benchmarks:

Beginner Milestones:

  • Row 20 minutes continuously with good form
  • 500m split time: 2:30-2:45 (men), 3:00-3:15 (women)
  • Complete 5k distance

Intermediate Milestones:

  • Row 45-60 minutes continuously
  • 500m split time: 2:00-2:15 (men), 2:30-2:45 (women)
  • Complete 2k test: under 8:00 (men), under 9:00 (women)

Advanced Milestones:

  • 2k test: under 7:00 (men), under 8:00 (women)
  • Maintain under 2:00/500m pace (men) or under 2:20/500m (women) for 30 min
  • Complete 10k+ distance

When to Refer or Modify:

  • Persistent low back pain despite form correction: refer to PT/physician
  • Rib pain that doesn't resolve with rest: medical evaluation for stress fracture
  • Knee pain during drive phase: check setup, reduce volume, evaluate for PT
  • Wrist pain persisting over 2 weeks: technique correction, possible PT referral
  • Inability to maintain form due to mobility: prioritize mobility work, reduce rowing volume
  • Users with significant spinal conditions: medical clearance before rowing

Damper Setting Guidance (Concept2):

  • Setting 1-3: Lower resistance, faster flywheel, more technique-focused (like rowing a single scull)
  • Setting 4-6: Moderate, most versatile for general fitness (like rowing a pair or four)
  • Setting 7-10: Higher resistance, heavier pull (like rowing an eight or for pure strength work)
  • Recommendation: Most people should stay 3-5; higher ≠ better workout

Mental Approach:

  • Rowing can be mentally challenging (repetitive, sometimes uncomfortable)
  • Metrics-driven: use splits, stroke rate, heart rate for engagement
  • Interval work helps break monotony
  • Music or video entertainment for steady-state
  • Competitive users: concept2.com logbook for virtual competitions
  • Emphasize technique mastery as ongoing challenge
