One Leg Donkey Calf Raise
- Beginner
- Isolation
- Rep-based
- Hips
- Lower legs
This unilateral variation isolates the gastrocnemius and soleus by using a hinged torso position to maximize the stretch on the calf. It is highly effective for correcting bilateral imbalances and improving ankle stability through a deep range of motion.

Setup
- Stand facing a flat bench and hinge at the hips until your torso is nearly parallel to the floor.
- Place your forearms or hands on the bench for support, keeping your back flat and core engaged.
- Lift one foot off the floor and hook it behind the ankle of the standing (working) leg.
- Position the ball of the working foot firmly on the floor or on the edge of a slight elevation if available.
How to do it
- Exhale as you press through the ball of your foot to raise your heel as high as possible.
- Squeeze the calf at the top of the movement for a one-second pause to maximize peak contraction.
- Inhale as you slowly lower your heel back to the starting position with a controlled 2-3 second tempo.
- Complete the desired number of repetitions on one leg before switching to the other.
Form checklist
- Keep the working knee slightly soft (not locked) to focus tension on the muscle belly.
- Maintain a neutral spine and avoid rounding your lower back while leaning over.
- Ensure the weight stays centered over the big toe rather than rolling to the outer edge of the foot.
- Keep your hips square to the floor throughout the entire set.
Pro tips
- Pause for two seconds at the bottom stretch to dissipate the 'stretch reflex' from the Achilles tendon, forcing the muscle to do more work.
- Focus the mind-muscle connection on driving the ball of the foot into the floor as if you are trying to stand on your tiptoes.
Make it harder
- Perform the exercise on the edge of a step or weight plate to allow the heel to drop below the level of the toes for a deeper stretch.
- Hold a dumbbell in the hand on the same side as the working leg to add external resistance.
