Contrast training involves?

• A. Utilize heavy lift combined with light lift
• B. Only heavy lifts
• C. Only light lifts
• D. Cardio intervals

Answer: (A)

Contrast training builds power by pairing a heavy resistance exercise with a lighter, explosive movement within the same session. The heavy lift primes the nervous system and muscle fibers, creating a post-activation potentiation effect that lets the subsequent lighter movement be performed with greater speed and force than it would alone. This specific heavy–then–light sequence is what makes contrast training effective for improving power, unlike doing only heavy lifts, only light lifts, or cardio intervals, which don’t use that heavy-to-light contrast. In practice, you’d follow a heavy exercise with a lighter, high-velocity movement and allow sufficient rest between work bouts to recover and reap the potentiation benefits.
