Bulletproof Activation Circuit
A four-station injury-prevention warm-up — hamstring walks, Copenhagen holds, hop-and-stick landings, short accelerations — done properly, not as a queue-and-chat.

Objective
Activate the hamstrings, adductors and landing mechanics that protect players from the most common football injuries, finishing with accelerations so legs arrive at the session primed.
Set-up
Mark four station squares in the corners of a 30x30 area. Station 1: hamstring walk-outs over 10 yards. Station 2: Copenhagen side-plank holds in pairs. Station 3: hop-and-stick over a line of flat markers. Station 4: 10-yard accelerations finishing with a dribble out. Split the squad evenly across stations.
How it runs
- Work 45 seconds at each station, 15 seconds to rotate clockwise — the whole circuit twice through.
- Station 1: walking hamstring sweeps and single-leg RDL reaches, slow and tall.
- Station 2: Copenhagen hold — top leg on a partner's arm or a bag, hips high, 2 x 15 seconds per side.
- Station 3: hop forward off one leg, stick the landing for two full seconds, knee over toes, then hop again.
- Station 4: two-step lean-and-go accelerations to 10 yards, last rep collecting a ball and dribbling away at speed.
Coaching points
- Hamstring sweeps: tall spine, hinge at the hip, feel the stretch not a bounce.
- Copenhagen: body in one straight line — no sagging hips.
- Stick every landing silent and still before the next hop.
- Accelerations: first two steps explode, nose over toes.
Common mistakes
- Players race the hamstring walks and turn them into lunges — slow it down, the stretch is the exercise.
- Hips sag in the Copenhagen hold, loading the lower back instead of the adductors — shorten the lever and re-set the line.
- Landings collapse inward with the knee diving across the big toe — stick, hold two seconds, knee tracking over the laces.
Progressions
- Add a partner-resisted start (shirt hold) at the acceleration station.
- Progress hops to lateral and rotational hop-and-stick.
- Extend Copenhagen holds to 20–25 seconds with the bottom leg lifted.
Regressions
- Short-lever Copenhagen (knee on support instead of foot) for players new to it.
- Replace hops with low two-foot jumps focusing on soft landings.
- Cut to one round of the circuit on heavy-fixture weeks.
Constraints
- Quality gate: any rushed, sloppy rep is repeated — the circuit only counts at full control.
