🎯 Setup

Starting Position

1. Machine setup: Sit with balls of feet on platform edge
   • Knees positioned under pad
   • Pad should rest comfortably on lower thighs (just above knees)
2. Foot position: Balls of feet on platform edge
   • Toes forward: Balanced development (default)
   • Toes out: Inner soleus emphasis
   • Toes in: Outer soleus emphasis
3. Knee position: 90° hip and knee flexion
4. Starting position: Heels dropped below platform level (stretch)
5. Load selection: Moderate weight to start

Equipment Setup

Equipment	Setting	Notes
Knee pad	Comfortable on thighs	Not on knee joint itself
Platform	Allows heel drop	3-4" drop minimum
Weight	Moderate	Soleus is an endurance muscle

Setup Cue

"Sit tall, balls of feet on edge, heels hanging low, knees snug under pad"

🔄 Execution

The Movement

⬇️ Lowering

What's happening: Controlled stretch of soleus

1. Slowly lower heels below platform level
2. Feel maximum stretch in deep calf
3. Don't bounce — controlled stretch
4. Breathing: Inhale on the way down

Tempo: 2-3 seconds

Feel: Deep stretch in lower calf, achilles area

⏸️ Bottom Position

What's happening: Full stretch position

1. Heels as low as comfortable
2. Brief pause (0.5-1 second)
3. Don't bounce or use momentum
4. Feel the stretch

Common error here: Bouncing to initiate the lift

⬆️ Rising

What's happening: Ankle plantarflexion from seated position

1. Push through balls of feet
2. Rise as high as possible
3. Focus on squeezing the deep calf
4. Breathing: Exhale as you rise

Tempo: 1-2 seconds (smooth, controlled)

Feel: Deep burn in soleus (lower/inner calf)

🔝 Top Position

What's happening: Peak contraction

1. Risen as high as possible
2. Squeeze calves hard
3. Hold for 0.5-1 second
4. Maximum ankle extension

Key: Full contraction for maximum soleus activation

Key Cues

Primary Cues

• "Heels to the floor" — maximize stretch
• "Press knees up" — think about lifting the pad
• "Squeeze and hold" — peak contraction

Tempo Guide

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

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Soleus	Ankle plantarflexion with bent knee	█████████░ 95%

Secondary Muscles

Muscle	Action	Activation
Gastrocnemius	Assists plantarflexion (less active when knee bent)	████░░░░░░ 35%

Stabilizers

Muscle	Role
Ankle stabilizers	Maintain alignment during movement

Muscle Emphasis

Why seated targets soleus: The gastrocnemius crosses both the knee and ankle joints. When the knee is bent (seated position), the gastrocnemius is in a mechanically disadvantaged position, forcing the soleus to do most of the work.

Standing vs Seated: Standing = gastrocnemius emphasis, Seated = soleus emphasis. You need BOTH for complete calf development.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Bouncing at bottom	Using momentum	Achilles stress, less muscle work	Controlled tempo, pause at stretch
Partial ROM	Not getting full stretch or rise	Minimal soleus development	Full stretch, full contraction
Too fast	Racing through reps	Poor activation	Slow tempo, feel each rep
Not pausing at top	Missing peak contraction	Less growth stimulus	Hold 0.5-1s at top
Sliding forward	Hips moving forward on seat	Changes angle, reduces effectiveness	Sit back, stable position

Most Common Error

Using too much weight and bouncing — the soleus is an endurance muscle. It responds better to controlled, moderate-weight reps with perfect form than heavy, sloppy bouncing.

Self-Check Checklist

• Full stretch at bottom (heels below platform)
• No bouncing or momentum
• Rising as high as possible
• Pausing at top
• Sitting stable, not sliding

Rep Ranges by Goal

Goal	Sets	Reps	Rest	Load	RIR
Hypertrophy	3-5	12-25	60-90s	Moderate	1-3
Endurance	3-5	25-50+	45-60s	Light-Moderate	2-4
Pump	4-5	20-30	30-45s	Light	2-3

Workout Placement

Program Type	Placement	Rationale
Leg day	After standing calf raises	Hit both calf muscles
Any workout	End	Can add to any session
Specialization	Multiple times per week	High frequency for stubborn calves

Frequency

Training Level	Frequency	Volume Per Session
Beginner	2x/week	3 sets
Intermediate	3x/week	3-4 sets
Advanced	4-6x/week	3-4 sets per session

High Frequency Note

Soleus is built for endurance (predominantly slow-twitch fibers). It recovers quickly and responds well to frequent training. You can train it 4-6x per week if volume per session is reasonable.

Progression Scheme

Progressive Overload

The soleus is an endurance muscle. Progress by adding reps (up to 30-50) before adding weight. When you can do 4x25 with perfect form, add weight and drop back to 3x12-15.

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Achilles tendinitis	Aggravation of tendon	Reduce stretch depth, lighter weight
Calf strain	Re-injury	Very light weight, limited ROM
Knee issues	Pressure on knees from pad	Adjust pad position, use towel for cushion

Stop Immediately If

• Sharp pain in achilles tendon or calf
• Knee pain from pad pressure
• Numbness or tingling in foot
• Sudden muscle cramping (stop, stretch, hydrate)

Form Safety Tips

Tip	Why
Don't bounce	Protects achilles tendon
Control the negative	Prevents strain
Proper pad placement	Avoids knee discomfort
Gradual stretch depth	Build up ROM safely

Safe Failure

How to safely stop a set:

1. When fatigued: Lower heels, engage safety catch, release pad
2. If cramping: Stop immediately, straighten legs, stretch calf
3. At failure: Machine prevents dangerous failure

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Ankle	Plantarflexion	20-40°	🟡 Moderate
Knee	Static hold (90° flexion)	None (stable)	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Ankle	20° plantarflexion	Can rise on toes while seated	Rare limitation
Ankle	10° dorsiflexion	Affects stretch depth	Reduce stretch if limited

Joint Health Note

If you have knee discomfort from the pad, place a towel on your thighs for cushioning, or adjust the pad to sit lower (just above knees, not on kneecaps).

❓ Common Questions

What's the difference between seated and standing calf raises?

Standing calf raises primarily target the gastrocnemius (the visible "diamond" calf muscle). Seated calf raises target the soleus (deeper calf muscle beneath the gastrocnemius). When your knee is bent, the gastrocnemius can't contribute much, so the soleus does the work. You need BOTH exercises for complete calf development.

How much weight should I use?

The soleus is an endurance muscle, so it responds well to moderate weights and higher reps (15-30+). Start light (maybe 25-50 lbs) and focus on full ROM and control. You should feel a deep burn in the lower/inner part of your calf. Don't ego-lift — form and ROM matter more than weight.

Why do my calves cramp during this exercise?

Calf cramps during training usually indicate: (1) Dehydration, (2) Electrolyte imbalance (low potassium/magnesium), (3) Doing too much volume too soon. Fix: hydrate well, consider electrolytes, build volume gradually. If cramping happens, stop, gently stretch, and reduce intensity next session.

Can I do seated calf raises every day?

Yes, the soleus recovers quickly due to its high slow-twitch fiber composition. Many advanced lifters do calf work (including seated raises) 5-6x per week. Keep volume per session moderate (3-4 sets) and listen to your body. If you're sore or performance drops, take a day off.

I only feel it in my toes, not my calves — what's wrong?

You're probably placing too much weight on the front of your foot (toes/ball of foot junction). The balls of your feet should be on the platform, but focus on pushing through the metatarsal heads (the bony area just behind your toes). Also, slow down and focus on the calf muscles doing the work.

For Mo

When to recommend this exercise:

• User wants complete calf development (must pair with standing raises)
• User is doing calf specialization program
• User has lower back issues (seated is easier than standing)
• User wants to improve calf endurance (running, walking, sports)

Who should NOT do this exercise:

• Acute achilles injury → Rest and rehab first
• Severe achilles tendinitis with pain → Modify ROM or wait for healing
• Recent calf strain → Wait for full recovery

Key coaching cues to emphasize:

1. "This hits the deep calf muscle — different from standing"
2. "Heels low, rise high, squeeze at the top"
3. "Moderate weight, higher reps — soleus loves endurance work"

Common issues to watch for in user feedback:

• "I don't feel it in my calves" → Reduce weight, slow tempo, check foot position
• "My calves cramp" → Hydration, electrolytes, reduce volume
• "Knee pad hurts" → Adjust pad position, use towel for cushion

Programming guidance:

• Pair with: Standing Calf Raise — essential pairing
• Avoid same day as: Not applicable — can train frequently
• Typical frequency: 3-6x per week

Progression signals:

• Ready to progress when: Can do 4x25 with perfect ROM, strong contraction
• Regress if: Form breaking down, achilles pain

Special note: Many users neglect the soleus, focusing only on standing raises. Emphasize that BOTH standing (gastrocnemius) and seated (soleus) are needed for complete calf development. The soleus adds significant mass beneath the gastrocnemius.
