Seated Calf Raise
The bent-knee calf raise hits the deeper muscle standing raises miss — do both, own both.
Setup
- Seated, balls of feet on the platform, pad (or dumbbell) on the knees.
How To Do It
- Lower heels to a FULL stretch — pause 2 seconds.
- Press up to full tiptoe; squeeze at the top.
- Slow tempo, high reps — the soleus likes patience.
Breathing
Exhale pressing up.
Common Mistakes
- Bouncing rhythm — the stretch pause is non-negotiable.
- Loading too heavy to reach full range.
Programming It
Three to four sets of 12-20 with a two-second pause at the top.
Why This Exercise Works
Bending the knee takes the gastrocnemius out of the equation, because it crosses the knee and goes slack. What is left is the soleus, which is the calf muscle that actually does the work in walking and running. Standing calf raises train the other one.
Where You Should Feel It
Deep in the calf, lower down than a standing raise, because the bent knee shifts the work to the soleus. A full stretch at the bottom is what makes it work.
Where It Fits in a Program
The bent-knee calf raise hits the deeper muscle standing raises miss — do both, own both. Slot it after the heavy work — it adds volume without stealing from anything.
Progressing and Regressing It
To progress the seated calf raise: add load, but never at the cost of the stretch at the bottom. To regress it: reduce the load and keep the full range; short reps do nothing here.
Who It's For
Anyone whose calves have not responded to standing work. The soleus is a large part of calf size and only bent-knee work reaches it properly.
Equipment and Substitutions
This version uses a machine or a dumbbell on knee. Any hand-held load will do — kettlebell, plate, or a filled bag. The related list below covers the machine versions.

Common Questions
What muscles does the seated calf raise work?
The seated calf raise primarily trains the calves (soleus).
How many sets and reps should I do?
Three to four sets of 12-20 with a two-second pause at the top.
What are the most common seated calf raise mistakes?
Most often: bouncing rhythm; loading too heavy to reach full range.
Do I need a machine or a dumbbell on knee to do this?
This version uses a machine or a dumbbell on knee, and it trains the calves (soleus). No dumbbells? A kettlebell of similar weight works for almost all of this, and the cable and machine versions below cover the rest.
Is this safe if I have an existing injury?
The seated calf raise loads the knee and ankle, so stiff ankles or an irritable knee will show up early. Sharp pain at a single point is the one to stop for; a general burn is not. Not medical advice.
