Pairs (or quads) a heavy strength lift with an explosive/plyometric movement in the same muscle pattern, performed back-to-back to exploit post-activation potentiation for greater power output.
How it works
In basic contrast training, perform a heavy strength set (e.g. 3-5 reps at 85%+ 1RM) immediately followed by an explosive movement in a similar pattern (e.g. jump squat) after a short rest (10-20s). French Contrast extends this to four exercises per pattern in sequence: 1) heavy strength lift, 2) plyometric, 3) weighted/accelerated plyometric (e.g. band-resisted or weighted jump), 4) unweighted maximal plyometric — cycling through all four before resting fully and repeating.
Pros
- Directly trains rate of force development / power, not just max strength
- Leverages post-activation potentiation for better plyometric output
- Efficient way to combine strength and power work in one session
- Strong track record in sprint/jump sport athletic development
Cons
- Requires a solid strength base before adding plyometric loading
- High technical/coordination demand across four different movement qualities
- Needs careful load and rest management to avoid injury
Best for
Examples
- French Contrast: Back Squat 3@85%, Squat Jump x5, Band-Resisted Jump x5, Max Height Jump x5 — rest 3 min, repeat 3-4 rounds
- Basic contrast: Trap Bar Deadlift 3 reps heavy, rest 15s, Broad Jump x3
Notes
French Contrast is credited to French national teams' sprint/jump coaches and was popularized in English-language strength & conditioning by Cal Dietz and other performance coaches.
