Accelerate.
Stop dead.
Nothing tears.

The first and last strides of every sprint — where quadriceps and groins are injured.

Deceleration is the missing dose

Most thigh rehabilitation never trains stopping. Stopping is a quadriceps task at the highest loads the leg meets.

Flares are normal

A flare that settles within 24–48 hours is sensitivity, not new damage. Hold the level, do not stop.

The adolescent exception

In a growing athlete, groin or thigh pain with a sudden pop can be a bone growth-plate avulsion rather than a muscle tear.

Go

Accelerations + falling start
A1

Acceleration steps

60 s · slow reps

Three hard driving steps from standing, walk back, repeat — count the sets.

Easier two steps, slower  ·  Harder five steps

A2

Falling start

8 reps · ×2

Lean forward until you have to step, then drive three fast steps and walk back.

Easier smaller lean  ·  Harder more steps

Lateral bound and stick + skater bounds
B1

Lateral bound and stick

60 s · slow reps

Push off the outside foot, cover ground, land and hold two seconds.

Easier small side step  ·  Harder further

R1R2—
B2

Skater bounds

10/side · ×2

Continuous side-to-side bounds landing soft on one leg with the hip level.

Easier step, no hop  ·  Harder further

Stop

Deceleration stops + single-leg landing
C1

Deceleration stops

60 s · slow reps

Three quick steps then stop dead, hips back, and freeze for two seconds.

Easier slower approach  ·  Harder faster approach

Single-leg landing hold

5 × 8 s/side · ×2

Hop once and freeze — hip back, knee over the toes, pelvis level.

Easier two-foot landing  ·  Harder bigger hop

Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.

How to run it

  1. Sprinting and kicking are where quads and groins tear, so both are trained deliberately and last.
  2. Two fast sessions a week, never on consecutive days.
  3. Any grab or pull at speed — stop the session and drop back a phase.
  4. Keep the squeeze test and one Copenhagen set a week for life. That is the maintenance dose.
