Triphasic Training Program
Triphasic training teaches athletes to absorb force, stabilize it, then release it fast. When you build control first, you gain speed, power and fewer overuse setbacks across court and field sports.
Why triphasic training works
Every explosive move has three parts: an eccentric lowering, a brief isometric transition, then a concentric lift or push. Training each phase builds the ability to stop quickly, hold optimal joint angles and apply force on time. If your team already lifts, layering these phase goals turns general strength into sport speed. For a primer on building fast force, review EvoFitLab’s guide to Rate of Force Development Training. For movement preparation ideas, see the Four Worlds Movement Framework.
Phase 1: Eccentric strength
Goal: absorb force with control so landings, stops and direction changes feel smooth.
How to train it: slow lowers on big lifts, landing drills that teach quiet feet, decel sprints.
Sample tools
- Back squat with 5 second lower, 3–5 sets of 3–5 reps
- Eccentric pull ups, 3–4 sets of 4–6 reps
- Depth drops to soft landing, 3 sets of 3–5 reps
- Deceleration runs, mark a stop line and stick it
Coaching cues
- Own the bottom position, keep ribs stacked over pelvis
- Land like a spring, not a stump

Phase 2: Isometric strength
Goal: create stiffness at the right angle so force transfers instead of leaking.
How to train it: paused lifts, split squat holds, overcoming isometrics against immovable pins.
Sample tools
- Split squat hold at 90 degrees, 3 sets of 20–40 seconds per side
- Pause deadlift with 2–3 second hold just off the floor, 3–4 sets of 3–5 reps
- Isometric mid-thigh pull, 3–5 efforts of 3–5 seconds
- Plank and side plank progressions, 3 sets of 30–45 seconds
Coaching cues
- Breathe low and wide, keep posture tall
- Drive hard without losing the set joint angle
Phase 3: Concentric power
Goal: turn stored energy into speed and height.
How to train it: jumps, throws and fast lifts with intent.
Sample tools
- Trap bar jump, 4 sets of 3–5 reps
- Med ball chest pass and scoop toss, 3–4 sets of 4–6 reps
- Flying sprints or sled sprints, 4–6 reps of 10–30 m
- Box jump with stick landing, 3–4 sets of 3–5 reps

12-week Triphasic Training Program
The Triphasic Training Program runs in three four-week blocks. Keep weekly volume honest and move best reps fast.
| Block | Weeks | Main focus | Strength lifts | Speed and plyo focus |
|---|---|---|---|---|
| Eccentric | 1–4 | Controlled lowering, decel skill | Back squat, bench, pull up with 5 s lowers | Depth drops, decel runs, low amplitude hops |
| Isometric | 5–8 | Stiffness at key joint angles | Pause front squat, pause deadlift, split squat holds | Wall sprint drills, paused broad jumps |
| Concentric | 9–12 | Ballistic intent and fast SSC | Trap bar jump, push press, med ball throws | Flying sprints, contrast jumps |
Weekly rhythm example
- Mon Strength A plus short tempo run
- Tue Speed mechanics and low dose plyo
- Thu Strength B plus med ball work
- Fri Sprint work and reactive jumps
- Sat Full body strength plus conditioning
- Wed and Sun active mobility or rest
Coaching and monitoring tips
- Film two angles on jumps and sprints to audit shin angle, torso position and landing quality
- Progress load or complexity only when landings stay silent and positions stay tall
- Track a simple KPI each phase such as vertical jump, 10 m time or reactive strength index
- Push athletes who need stiffness in phase 2, push athletes who need pop in phase 3
