Heel-drop (eccentric) and heavy slow calf exercises are the backbone of Achilles tendon rehab. Moderate pain during exercise (up to about 5 out of 10) is acceptable if it settles by the next morning.
The classic heel-drop programme
| Exercise | How | Dose |
|---|---|---|
| Straight-knee heel drop | Stand on a step, rise on both feet, lower slowly on the sore leg | 3 x 15, twice a day |
| Bent-knee heel drop | Same, with the knee slightly bent | 3 x 15, twice a day |
Continue for 12 weeks. Add a backpack with weight as it gets easier.

Alternatives
- Heavy slow resistance: seated and standing calf raises with weight, 3 to 4 sets, every other day
- Isometric holds for painful days
For insertional pain (where the tendon meets the heel), do the drops on flat ground, not off a step.
