Achilles Tendinopathy Rehab Program

Achilles Load Restoration™

A 16-Week Return-to-Performance System

Four progressive 4-week phases that rebuild your Achilles tendon's load tolerance, unilateral strength, and pre-elastic readiness — before you return to running or jumping.

WHERE THIS FITS

Your Achilles Rehab Pathway

​

Achilles Load Restoration™ sits between early off-loading and elastic / running-based work. It is the phase most commonly skipped — and the reason most Achilles rehab programs stall or relapse.

STEP 1

Acute off-loading & early rehab

Are you here?
Phase 1 Achilles Load Restoration

Phase 2 Achilles Load Restoration

Phase 3 Achilles Load Restoration

Phase 4 Achilles Elastic Capacity

Tendons adapt slowly. Meaningful collagen remodelling takes approximately 12 weeks of consistent, progressive loading. This program respects that timeline — building from bilateral isometrics to high-load unilateral strength before any elastic or plyometric demand is introduced. It goes beyond 12 weeks to bridge across to a return to running and sport.

THE PROGRAM

Four Phases. One System. No Shortcuts.

Each phase has a specific training focus and a measurable strength checkpoint that must be achieved before progressing. Progression is earned — not assumed.

Phase 1 of 4  ·  Weeks 1–4

Foundational Load Restoration

Focus: Bilateral & isometric loading

Re-introduce load with bilateral and assisted exercises. Longer isometric holds reduce pain sensitisation and begin restoring tendon tolerance. The tendon is treated as reactive — all loading is deliberate and controlled.

EXIT CHECKPOINT

 

Single-leg isometric heel raise hold at 100% bodyweight for 30 seconds — pain-free, no next-day flare.

USD $59

Phase 2 of 4  ·  Weeks 5–8

Unilateral Capacity & Consolidation

Focus: Single-leg strength & time under tension

Unilateral loading begins. Loaded isometrics, slow eccentrics, and longer time-under-tension sessions build true single-leg Achilles capacity. This phase forms the bridge between early tolerance work and the demands of pre-elastic training.

EXIT CHECKPOINT

 

Single-leg isometric heel raise hold at 1.2× bodyweight for 30 seconds — confident, no compensation.

USD $59

Phase 3 of 4  ·  Weeks 9–12

Pre-Elastic Readiness

Focus: High-load strength & elastic entry

Positional strength, angle-specific control, and neuromuscular precision. 
Deep-range loading at 1.5× bodyweight, longer levers, and the first controlled exposure to speed — all under strict integrity criteria. 
The launchpad for Elastic Capacity™.

EXIT CHECKPOINT

 

Single-leg isometric at 1.5× bodyweight for 30 seconds. 6–8 slow reps with added load. Tolerance of mini-hops.

USD $59

Phase 4 of 4  ·  Weeks 13–16

Elastic Capacity

Focus: Elastic loading & controlled running exposure

Bilateral to unilateral plyometric progression with controlled elastic loading. Short acceleration efforts capped at 6 seconds, fast stretch-shortening cycles, and movement rhythm — all before continuous running resumes. The bridge between rehab and return to sport.

EXIT CHECKPOINT

 

Tolerates continuous plyometrics and single-leg elastic loading. 

Running exposure introduced and capped at ~6 seconds. 

Ready for short-to-long running progression.

IS THIS RIGHT FOR YOU?

Who This Program Is For

​

✓ This program suits you if:

​

✓ You have chronic or sub-acute Achilles tendinopathy (mid-portion or insertional)

✓ You've finished acute rest or boot use and are ready to reload

✓ Running, jumping, or change of direction is still painful

✓ Previous rehab has stalled or symptoms keep returning

✓ You want an active, structured exercise-based approach

✓ You're willing to commit 12 weeks and follow the progression criteria

✕ This program is not for you if:

​

✕  You are in an acute flare with significant swelling or severe pain at rest
✕  You can already run and jump pain-free (consider Elastic Capacity™ instead)
✕  You want a quick fix and won't follow the phase checkpoints
✕  You plan to push through sharp or escalating pain

HOW IT WORKS

Each Session. Every Phase.

Every training session across all three phases follows the same structured format — so you always know what to expect and why.

① Reset / Isometric Holds

Gentle isometric calf exercises reduce pain sensitivity and activate the tendon before loading begins. These are not warm-up fillers — they serve a specific neurological purpose.

​

② Movement Prep

Dynamic ankle mobility and range-of-motion drills prepare the tissue for the loading block. Ankle rocks, heel lowers, and controlled dorsiflexion work are standard inclusions.

​

③ Main Loading Block

The core of each session. Calf raises progressing from bilateral isometric holds to slow isotonic single-leg work, with load increased based on your tolerance — not the calendar.

​

④ Cooldown & Symptom Check

Each session ends with a guided self-assessment. You rate your pain response, morning stiffness, and confidence — and use that to decide whether to progress or repeat next session.

Progression Rules — Read Before You Purchase

​

→  Pain during exercises must be ≤ 4/10 to progress. Moderate discomfort is acceptable; sharp pain is not.

→  Any discomfort must ease during or shortly after the session — no persistent worsening.

→  No significant increase in morning stiffness or pain the following day.

→  You feel more confident loading your Achilles, not more apprehensive.

→  If these criteria are not met: repeat the session or week. This is not failure — it is intelligent load management.
