Midportion Achilles Tendinopathy Exercises

Progressive tendon loading is first-line care for midportion Achilles tendinopathy. This plan uses straight-knee and bent-knee calf work, gradual resistance, and morning stiffness as a load signal.

Use two calf angles and one clear progression.

Perform the straight-knee and bent-knee loading exercises on the same day. Use the isometric hold as an entry option on more painful days, not as mandatory extra volume. Keep all work on a flat floor for this midportion starter plan.

Frequency
Loading at least 3 days per week
Equipment
Wall or counter, chair, optional backpack or dumbbell
First checkpoint
Commit to at least 12 weeks
Primary goal
Stronger push-off, walking, stairs, running, and jumping
  1. Exercise 1

    Optional calf-raise isometric hold

    On more painful days

    Dose4 holds of 20 to 30 seconds

    Rise onto both forefeet on a flat floor and hold at a comfortable height while using a counter for balance. Keep pressure even across the forefoot.

    Make it easier

    Hold lower or shift more weight to the less painful side.

    Progress it

    Shift more weight toward the involved side.

  2. Exercise 2

    Slow straight-knee heel raise

    At least 3 days per week

    Dose3 sets of 8 to 15 repetitions

    With knees straight and support nearby, rise for two to three seconds and lower for two to three seconds. Start with both legs.

    Make it easier

    Use more hand support or a smaller range.

    Progress it

    Progress to one leg, then add a backpack or dumbbell.

  3. Exercise 3

    Slow bent-knee heel raise

    At least 3 days per week

    Dose3 sets of 8 to 15 repetitions

    Keep a small, steady bend in both knees while lifting and lowering the heels slowly. Keep the knees over the middle toes.

    Make it easier

    Use a wall sit position with a smaller heel lift.

    Progress it

    Shift toward one leg or add external load.

  4. Exercise 4

    Single-leg heel raise progression

    3 days per week when ready

    Dose3 sets of 6 to 12 repetitions

    Rise and lower on one leg with a slow tempo, stable ankle, and similar heel height across repetitions.

    Make it easier

    Use the other foot lightly for assistance.

    Progress it

    Add load while preserving height and control.

  5. Exercise 5

    Later-stage pogo or hop

    2 to 3 days per week when ready

    Dose2 to 3 sets of 15 to 20 contacts

    Begin with small two-leg springing contacts. Keep the rhythm quiet and controlled. Add this only after walking, stairs, and repeated single-leg heel raises are tolerated.

    Make it easier

    Use brisk marching or quick heel raises without leaving the floor.

    Progress it

    Progress toward single-leg or activity-specific hopping.

Let the next day guide the dose.

Some tendon discomfort during loading can be acceptable when mechanics remain controlled and next-morning pain or stiffness does not increase. Complete rest is usually unnecessary.

Continue

Green light

Tolerable discomfort, good heel-raise control, and morning pain or stiffness that is unchanged or improving.

Adjust

Yellow light

Next-morning pain or stiffness increases, the heel-raise height falls, or running and strengthening together create a cumulative flare. Reduce load or total contacts.

Stop

Red light

Stop. Call 911 for chest pain, trouble breathing, fainting, or another medical emergency. Seek same-day urgent assessment for new one-sided calf swelling, a sudden pop, new bruising, a palpable gap, or inability to push off.

Change one variable at a time

When symptoms are too reactive, first reduce range, resistance, repetitions, or frequency. When the current dose feels controlled for several sessions, progress only one of those variables.

Build capacity in stages.

  1. Stage 1: establish a tolerable load

    Use two-leg slow raises and optional isometric holds. Continue general activity within pain tolerance rather than resting completely.

  2. Stage 2: increase tendon strength

    Progress from two legs to one leg, then add external load. Choose a resistance that makes the final repetitions challenging while controlled.

  3. Stage 3: restore spring and sport

    Add fast calf work, pogo contacts, hopping, and running volume only after slow strength and daily activities are stable.

Signs you are ready for the next stage

  • Morning pain and stiffness are stable or improving.
  • Repeated single-leg heel raises have good height and control.
  • Walking and stairs do not produce a sustained flare.
  • You can add load without losing the slow tempo.

When to schedule an evaluation

Schedule a visit if the pain is at the heel attachment, the diagnosis is uncertain, symptoms are worsening, a rupture is possible, or a consistent twelve-week loading trial does not improve function.
