🎯 Setup

Starting Position

1. Initial position: Perform leg press set OR set up for calf raises only
   • Knees fully extended (straight legs)
2. Foot position: Only balls of feet on bottom edge of platform
   • Heels hanging off completely
3. Stance: Feet hip-width apart, toes straight ahead
4. Leg position: Knees locked out (straight but not hyperextended)
5. Hand position: Grip handles for stability
6. Safety: Unlock sled, control with legs straight

Equipment Setup

45-Degree Press

Component	Setting	Notes
Seat	Reclined position	Standard leg press position
Foot Position	Lower edge of platform	Toes only, heels hanging
Weight	Moderate to heavy	Can go heavier than standing
Safety	Unlocked for movement	Keep handles engaged

Most common type — angled sled moves on rails

Horizontal Press

Component	Setting	Notes
Seat	Fully back	Standard press position
Foot Position	Bottom of platform	Balls of feet only
Weight	Same as 45-degree	Adjust for machine type

Note: Horizontal presses work the same way

Vertical Press

Component	Setting	Notes
Lying Position	Flat on back	Less common machine
Foot Position	Platform overhead	Careful with foot placement
Weight	Conservative	Safety critical

Caution: Vertical presses require extra care — weight is overhead

Setup Cue

"Knees locked, toes on edge, heels hanging free — now you're a calf-raising machine"

🔄 Execution

The Movement

🔧 Setup Phase

What's happening: Positioning for controlled calf work

1. Finish leg press set (or set up with knees extended)
2. Walk feet down to lower edge of platform
3. Position balls of feet on edge, heels hanging off
4. Knees fully extended (locked but not hyperextended)
5. Grip handles for stability

Tempo: Deliberate positioning

Feel: Weight on balls of feet, stable position

⬆️ Push Phase

What's happening: Plantar flexion pushing sled away

1. Push through balls of feet
2. Extend ankles fully — push sled as far as possible
3. Squeeze calves hard at peak
4. Breathing: Exhale as you push

Tempo: 1-2 seconds (controlled, powerful)

Feel: Strong contraction in gastrocnemius (upper calf)

Critical: Full ankle extension — don't short the range

🔝 Peak Contraction

What's happening: Maximum gastrocnemius contraction

1. Sled pushed fully away
2. Ankles fully extended (plantarflexed)
3. Hold 1-2 seconds
4. Squeeze calves maximally

Common error here: Not pushing far enough. Get full extension.

⬇️ Lowering

What's happening: Controlled sled descent with calf stretch

1. Lower sled slowly by dorsiflexing ankles
2. Allow heels to drop as far as possible
3. Feel deep stretch in calves
4. Breathing: Inhale on the way down

Tempo: 2-3 seconds (slow, controlled)

Feel: Deep stretch in gastrocnemius and soleus

Note: The stretch is crucial — let heels drop as far as comfortable

Key Cues

Primary Cues

• "Knees locked, push through toes" — isolate calves only
• "Full stretch, full squeeze" — maximize ROM
• "Control the sled, no bouncing" — quality reps

Tempo Guide

Goal	Tempo	Example
Strength	2-0-2-1	2s up, no pause, 2s down, 1s stretch
Hypertrophy	2-2-3-2	2s up, 2s pause, 3s down, 2s stretch
Endurance	1-0-2-1	1s up, no pause, 2s down, 1s stretch

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Gastrocnemius	Plantar flexion with knees extended — primary ankle extensor	█████████░ 90%

Secondary Muscles

Muscle	Action	Activation
Soleus	Assists with plantar flexion	██████░░░░ 65%

Stabilizers

Muscle	Role
Tibialis Anterior	Stabilizes ankle during movement
Quads	Maintain knee extension (isometric hold)

Muscle Emphasis

Leg press vs other calf exercises:

• Leg Press: Heavy loading, gastrocnemius emphasis (knees straight)
• Standing Calf Raise: Similar but less stable, lighter loads
• Seated Calf Raise: Soleus emphasis (knees bent)

Benefits of leg press variation:

• Stable platform allows heavier loads
• Convenient — already using leg press
• Safe — can't lose balance like standing variations
• Progressive loading easy

Toe position:

• Straight: Balanced development
• Toes out: Medial (inner) emphasis
• Toes in: Lateral (outer) emphasis

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Bending knees	Turns into partial leg press	Reduces calf isolation, defeats purpose	Lock knees, ankles only
Partial ROM	Not getting full stretch or contraction	Limits muscle development	Drop heels deep, push sled fully
Bouncing at bottom	Using momentum	Reduces muscle tension, Achilles risk	Controlled pause at stretch
Feet too high on platform	Can't get full ROM	Limits effectiveness	Balls of feet only, on lower edge
Not securing position	Sled slips, foot slides	Safety risk	Proper foot placement, controlled movement

Most Common Error

Bending knees during movement — this defeats the purpose of isolating the calves. Keep knees locked throughout. Only the ankles should move.

Self-Check Checklist

• Knees fully extended and locked (not hyperextended)
• Only balls of feet on platform edge
• Heels drop well below platform level (full stretch)
• Sled pushed fully away (full contraction)
• No knee bending during reps
• Controlled tempo, no bouncing

📊 Programming

Rep Ranges by Goal

Goal	Sets	Reps	Rest	Load	RIR
Strength	3-4	10-15	90s-2min	Heavy	1-2
Hypertrophy	4-5	15-25	60-90s	Moderate-Heavy	2-3
Endurance	3-4	25-40+	45-60s	Light-Moderate	3-4

Workout Placement

Program Type	Placement	Rationale
Leg day	Immediately after leg press	Already set up, convenient
Lower body	End of workout	Calf work doesn't interfere with main lifts
Calf specialization	After main calf exercise	Secondary calf movement

Programming Tip

Perfect pairing: Do calf raises immediately after your final leg press set. You're already positioned, loaded, and warmed up. Extremely efficient.

Calf frequency: Can train calves 3-4x per week. Alternate between leg press (gastrocnemius) and seated (soleus) variations.

Frequency

Training Level	Frequency	Volume Per Session
Beginner	2x/week	3 sets of 15-20 reps
Intermediate	3x/week	4 sets of 20-25 reps
Advanced	3-4x/week	4-5 sets of 20-30 reps

Progression Scheme

Progressive Overload

Leg press allows for heavy calf loading. You can often use 50-100% of your leg press weight just for calves. Progress by adding weight (10-20 lb jumps) or reps.

Sample Progression

Week	Weight	Sets x Reps	Notes
1	180 lbs	3x20	Establish baseline
2	180 lbs	4x20	Add set
3	200 lbs	4x20	Add weight
4	200 lbs	4x25	Add reps
5	220 lbs	4x20	Add weight, reset reps

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Achilles tendonitis	Stress on tendon	Reduce ROM, lighter weight
Knee injury	Holding knees locked	Use seated calf raises instead
Calf strain	Re-injury during stretch	Wait until healed, gradual ROM
Ankle instability	Loss of control with heavy weight	Lighter loads, focus on stability

Stop Immediately If

• Sharp pain in Achilles tendon
• Knee pain from locked position
• Foot slipping on platform
• Sled falling/loss of control
• Severe cramping that doesn't resolve

Injury Prevention

Strategy	Implementation
Secure foot position	Balls of feet firmly on edge, not slipping
Controlled movement	No bouncing, smooth tempo
Progressive loading	Add weight gradually
Full ROM carefully	Don't force extreme stretch initially
Lock knees properly	Extended but not hyperextended

Platform Safety

Critical safety points:

• Foot placement: Secure on edge, won't slip
• Weight control: Can handle the load throughout ROM
• Safety catches: Know where they are (emergency)
• Smooth surface: Platform not worn/slippery

Most Common Issue

Foot slipping on platform when using heavy weight or during deep stretch. Ensure secure foot position and use controlled tempo. Chalk on balls of feet can help if slipping is an issue.

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Ankle	Plantar Flexion/Dorsiflexion	30-40° total	🟡 Moderate
Knee	Extension (static hold)	0° (locked)	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Ankle	20° dorsiflexion	Can drop heels below platform	Ankle mobility work, gradual ROM progression

Joint Health Note

Leg press calf raises are very safe. The stable platform and supported body position reduce balance demands and allow focus on the ankle joint movement. Knee is held static in extension (minimal stress).

❓ Common Questions

Can I use my full leg press weight for calf raises?

Usually no. Most people use 40-70% of their leg press weight for calf raises. Start light and build up. Calves are smaller muscles — you'll use less weight, but can still go fairly heavy compared to standing calf raises.

Should I do calf raises after every leg press set?

Not necessarily. Options:

1. After final leg press set: Most common — finish legs, then do all calf sets
2. Superset: Alternate leg press and calf raises (time-efficient)
3. Separate: Do leg press, then other leg exercises, finish with calves

Choose based on your program and time.

Leg press calf raises vs standing calf raises — which is better?

Both target gastrocnemius. Differences:

• Leg press: More stable, can go heavier, convenient if already using leg press
• Standing: More functional (standing position), requires balance, typically lighter

Neither is "better" — use what's available or both for variety.

Why do my calves cramp during this exercise?

Common reasons:

1. Dehydration — drink more water
2. Electrolyte imbalance — ensure adequate sodium, potassium, magnesium
3. Too much volume too soon — build gradually
4. Insufficient warm-up — warm up calves before heavy sets

If cramping persists, reduce weight and volume, ensure proper hydration and nutrition.

Should I keep my knees completely locked?

Yes, knees should be fully extended (straight) throughout the movement. This ensures gastrocnemius activation. However, "locked" doesn't mean hyperextended — just straight. If bending knees, you're doing a partial leg press, not a calf raise.

How do I know if I'm using enough ROM?

Full ROM checklist:

• Bottom: Heels drop noticeably below platform level (you should feel a strong stretch)
• Top: Ankles fully extended (plantarflexed), sled pushed as far as possible

If you're not getting both, increase ROM before adding weight.

For Mo

When to recommend this exercise:

• User is already doing leg press — extremely convenient
• User wants heavy calf loading in stable environment
• User wants gastrocnemius development
• User has leg press available in their gym

Who should NOT do this exercise:

• Knee injury preventing locked position → Use Seated Calf Raise
• No leg press access → Use standing calf raise or other variations
• Acute Achilles injury → Wait until healed

Key coaching cues to emphasize:

1. "Knees locked — only ankles move"
2. "Balls of feet on edge, heels hanging free"
3. "Deep stretch at bottom, full push at top"
4. "Control the sled, no bouncing"

Common issues to watch for in user feedback:

• "Knees are bending" → Cue to lock knees, may need less weight
• "I don't feel it" → Check ROM and foot position
• "My feet slip" → Better foot placement, chalk, or slower tempo
• "Cramping" → Hydration, electrolytes, reduce volume

Programming guidance:

• Pair with: Seated calf raises for complete development, or do immediately after leg press
• Frequency: 2-3x per week
• Place at end of leg press workout or end of leg day
• Volume: 3-5 sets of 15-25 reps

Progression signals:

• Ready to progress when: 4x20 with full ROM, 2 RIR
• Try single-leg when: Strong bilateral base (can do 4x25)
• Increase weight when: Perfect form, full ROM, 2 RIR

Red flags:

• Foot slipping during movement → immediate safety concern
• Knee pain from locked position → switch to seated variation
• Sharp Achilles pain → stop, assess injury
• Bending knees during reps → form correction needed
