Sled 45 Calf Press
Sled 45 Calf Press Video Guide
The Sled 45 Calf Press is a heavy, controlled calf exercise performed on a 45-degree leg press machine. With your feet placed low on the platform, the calf muscles — the gastrocnemius and soleus — move through a full range of motion without loading the spine. The angled sled provides back support, high resistance, and a deep stretched position at the bottom, making it one of the most effective calf-strengthening movements for size, stability, and ankle control. Because the movement is performed with the legs mostly straight, the gastrocnemius does most of the work, while the soleus contributes through ankle flexion and controlled extension.
This calf press variation improves lower-leg strength, enhances ankle stability, and allows you to safely use heavier weight while maintaining proper form. With consistent tempo and smooth motion, the exercise helps develop stronger calves for running, jumping, squatting, and overall athletic performance.
How to Perform the Sled 45 Calf Press
-
Set the starting position by sitting in the sled with your back supported and placing the balls of your feet low on the platform, heels hanging off the edge. Keep legs straight but knees soft, not locked.
-
Lower your heels slowly, letting them drop until you feel a deep stretch through the calves and Achilles tendon. Keep motion controlled.
-
Press through your toes to lift the sled by extending only at the ankles, keeping legs and hips completely still.
-
Hold at the top, squeezing the calf muscles for a brief moment to maximise contraction and stability.
-
Lower under control, returning to the stretched position without bouncing, then repeat for the desired repetitions.
GymNation Tip: Move with consistent tempo — slow eccentrics build far more strength than adding weight and rushing the movement.
Personal Trainer Notes:
-
Knees stay soft and stable — never locked.
-
Movement happens only at the ankles, not the knees or hips.
-
Avoid lifting the arches or rolling the feet. Maintain solid platform contact.
-
Control every rep — momentum removes tension.
-
Increase weight gradually to preserve form and range.

Alternative Calf Exercises
Barbell Seated Calf Raise
The Barbell Seated Calf Raise targets the soleus muscles (lower calves) and helps build strength and size in the lower leg. Performing this exercise seated ensures constant tension on the calves through a full range of motion.
Dumbbell Standing Calf Raise
The Dumbbell Standing Calf Raise strengthens the calves (gastrocnemius and soleus) while also challenging balance and coordination. It’s simple and effective anywhere.
Barbell Standing Leg Calf Raise
The Barbell Standing Leg Calf Raise strengthens the gastrocnemius (upper calf) for improved power and definition. It also enhances ankle stability and balance.
Lever Standing Calf Raise
The Lever Standing Calf Raise strengthens the gastrocnemius and soleus muscles for improved power, balance, and definition. The standing position targets the upper calves most effectively.
Lever Seated Calf Raise (Plate Loaded)
The Lever Seated Calf Raise (plate loaded) isolates the soleus (lower calves) through controlled seated motion. It’s great for strength and endurance development in the lower leg.
Weighted Donkey Calf Raise
The Weighted Donkey Calf Raise targets both the gastrocnemius and soleus. The bent position enhances stretch and muscle recruitment for fuller calf development.
Donkey Calf Raise
The Donkey Calf Raise builds both the gastrocnemius and soleus muscles for fuller, stronger calves. The bent-hip position increases the stretch for deeper activation.
Smith Standing Leg Calf Raise
The Smith Standing Leg Calf Raise builds the gastrocnemius for powerful and well-shaped calves. The Smith machine provides stability for controlled lifting.
Single Leg Calf Raise Off Step
The Single Leg Calf Raise Off Step isolates each calf individually, improving balance and preventing strength imbalances. It builds both the gastrocnemius and soleus for complete calf strength.
Sled 45 Calf Press FAQs
The exercise targets the gastrocnemius and soleus, improving calf strength, ankle control, and overall lower-leg stability. The angled sled increases resistance and stretches the calves through a longer range of motion.
The sled moves against gravity at a fixed angle, forcing the calves to work harder during both the lowering and pressing phases. This increases tension and produces stronger muscle activation.
Yes — as long as the knees stay soft, the heels lower slowly, and the ankles move through a controlled range. Locking the knees or rushing the stretch increases injury risk.
Feet low on the platform, heels down slowly, extend through the ankles only, squeeze at the top, then return with full control. Maintain the same position every rep.
Absolutely. Start with light weight, focus on form and range, and progress gradually as calf strength improves.
Perform 3–4 sets of 12–20 reps, focusing on deep stretching, smooth pressing, and controlled lowering for maximum effectiveness.
