Donkey Calf Raise
An old-school favorite from bodybuilding's golden era, the donkey calf raise loads the calves while you are hinged forward at the hips. That bent-over position stretches the gastrocnemius at both ends — the ankle and, via the hamstrings, the knee — producing a deeper loaded stretch than a standing raise can. Lifters who plateau on standing raises often find the donkey variation restarts growth.
How to do the donkey calf raise, step by step
- Set up in the donkey machine with your forearms on the arm pad and the back pad against your hips or lower back.
- Place the balls of your feet on the platform, heels hanging free, legs straight.
- Hinge to roughly 90 degrees at the hips so your torso is near parallel to the floor.
- Lower your heels into a deep stretch over 2 to 3 seconds and pause for a second.
- Drive up onto the balls of your feet as high as possible.
- Squeeze at the top, then lower under control and repeat.
Form cues that fix most reps
Stay hinged — the forward fold is the entire reason this variation exists.
Keep the knees straight so the stretch lands on the gastrocnemius, not the soleus.
Let the bottom stretch sink in for a full second before driving up.
Common mistakes (and the fix)
Donkey Calf Raise sets and reps
Match the rep range to your goal, not the other way around. These are the standard evidence-based ranges:
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 3–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 8–12 | 60–90 sec |
| Endurance | 2–3 × 15–20 | 30–60 sec |
Donkey Calf Raise FAQ
What muscles does the donkey calf raise work?
The gastrocnemius, loaded in its most stretched available position because the straight knees and hip hinge lengthen it across both joints it crosses. The soleus assists, but the bent-over stretch is a gastrocnemius specialty.
Donkey vs standing calf raise?
Both are straight-knee gastrocnemius exercises; the donkey's hip hinge adds hamstring tension that pulls the gastrocnemius even longer, and training muscles at long lengths is consistently associated with strong growth. If your gym has the machine, it is worth rotating in — 3 to 4 sets of 10 to 15 with a stretch pause.
No donkey machine at my gym — what can I do?
Recreate it: hinge at the hips with your forearms on a bench or rack, balls of the feet on a plate or block, and have a resistance setup or a smith machine pad across your hips. Even bodyweight, the bent-over stretch position done slowly for high reps is productive.
