One calf at a time on the sled gives a stubborn or smaller calf its own dedicated workload, something the two-foot leg press calf raise can never guarantee. Calves recover quickly, so reps run high, 12 to 20 per side works well, and the pause in the stretched bottom position is where the set is actually earned.
How to do the Single Leg Leg Press Calf Raise
- Adjust the seat of the leg press machine so that your knees are slightly bent when your feet are on the sled.
- Sit on the machine with your back against the backrest and your feet on the sled, shoulder-width apart.
- Place your toes and the balls of your feet on the sled, keeping your heels off.
- Push the sled forward by extending your ankles, keeping your knees slightly bent.
- Pause for a moment at the top, then slowly lower the sled back down by flexing your ankles.
- Repeat for the desired number of repetitions.
Tip: Push through the whole foot and keep your knees tracking in line with your toes rather than caving inward.
Muscles worked
Primary
Calves · Legs
On a leg press calf raise, the calves push the platform away with the ball of the foot; go for a full stretch at the bottom and a slow lowering.
Secondary
- Hamstrings
- Glutes — The glutes get more involved the higher and wider your feet are on the platform and the deeper you go.
Common mistakes
- Lower back peeling off — if your hips lift at the bottom, the range is too deep for your hip mobility; stop just before the pelvis tucks.
- Slamming into lockout — slamming to full extension under a heavy sled loads the joint, not the muscle; stop just short of lockout and keep tension.
- Feet too low — a low foot position pushes the knees far forward and shifts everything onto the quads and knees; move the feet up to bring in the glutes.
- Half reps, too much weight — the leg press invites ego loading, so pick a weight you can take to at least 90 degrees of knee bend with control.
Where it fits in a workout
Use the leg press after squats as a way to get more quad volume without the bracing demand, or as the main lower body lift on a lighter day. Follow each set with calf raises on the same sled to save time.
