Donkey Calf Raises
The donkey calf raise has you bend forward at the hips, torso roughly parallel to the floor, with resistance loaded across your hips while you raise and lower your heels. That forward-hinged position stretches the calf further at the bottom than a standing calf raise does, which is what makes it a favorite for anyone who feels standing raises stop working after the first few sets. It's a single-joint isolation move, so it's forgiving to load often once your balance and hip position are dialed in.
Why it works
Bending forward at the hips changes the angle of your ankle relative to your knee and hip compared to standing upright, which lets the calf lengthen further before you even start raising your heels. That extra stretch at the bottom of the rep is what separates the donkey raise from a standard standing calf raise, since more muscle length under tension tends to drive more growth for the same number of reps. The exercise isolates the calf almost entirely, with your hips and torso staying fixed in a forward lean so the ankle joint does essentially all the moving.
Set up
- Set your torso roughly parallel to the floor, supported at the hips, with your feet flat on a raised platform or step.
- Line up the front of each foot on the edge of a raised step, leaving your heels free to sink lower than it.
- Keep your knees soft, not locked, and your hips fixed in place before you start moving.
How to do it
- Let your heels drop as far below the platform as comfortably possible to start each rep stretched.
- Press through the balls of your feet and raise your heels as high as you can.
- Pause briefly at the top with your calves fully contracted.
- Lower under control back down to the stretched starting position.
- Keep your knees and hips still throughout; only your ankles should move.
Form cues
- Full stretch at the bottom, heels dropping below the platform.
- Full contraction at the top, pause briefly.
- Hips and knees stay fixed, only the ankle moves.
- Control the descent instead of dropping fast.
Breathing: Exhale as you press up onto your toes, inhale as you lower back into the stretch.
Common mistakes
Cutting the range short at the bottom and never letting the heels drop below the platform.
Fix: Slow down and let gravity pull your heels down into a full stretch before reversing each rep.
Bouncing out of the bottom stretch instead of controlling the transition.
Fix: Pause briefly at the bottom so the calf, not momentum, starts the next rep.
Bending the knees to help push the weight up.
Fix: Keep the knees soft but still; if you need knee bend to move the load, the weight is too heavy for strict form.
How to program it
- As a single-joint isolation exercise for a muscle that recovers quickly, 2 to 3 sessions a week of 10 to 15 reps per set works well for most people.
- Because the stretched bottom position is what makes this raise effective, prioritize full range over adding more weight when the two conflict.
- Pair it with a seated calf raise on a different day to hit the calf in both a straight-leg and bent-knee position across the week.
Safety notes
- Keep a firm, stable hold on your support or hip pad; the forward-hinged position makes you more likely to lose balance than a standing raise.
- If you feel strain in the lower back rather than the calves, check that your hips are staying still and your spine isn't rounding under the load.

Frequently asked questions
How many sets and reps of donkey calf raises should I do?
2 or 3 sets of 10 to 15 reps, done a couple of times a week, is a solid starting point. Calves respond well to volume, so consistency across the week matters more than any single heavy set.
What's the difference between donkey calf raises and standing calf raises?
The forward-hinged torso position in a donkey raise lets your heel drop into a deeper stretch at the bottom than a standing raise allows, which many lifters feel as a stronger calf contraction through the same range.
Can I do donkey calf raises at home without a machine?
You can approximate it by hinging forward with your hands on a table or wall for support and your toes on a raised step, though loading it with real weight is easier with a partner or a hip-belt setup.
Why don't I feel donkey calf raises in my calves?
It's usually a range-of-motion problem: cutting the bottom stretch short or bending the knees to help lift the weight both take tension off the calf. Slow down, let the heels drop fully, and keep the knees still.
