Why We Use Complementary Movements in strength & Conditioning components

If you’ve ever noticed lunges, KBS, or high volume lighter squats in the metcon after heavy squats, you might wonder: is this too much? why do we double up on the same muscle groups?

The answer: complementary movements make your strength training more effective.

When you squat heavy, you’re building maximum strength. Following it up with lighter, higher-volume work in conditioning challenges your muscles in a different way. This combination:

• Reinforces strength gains – hitting the same muscles from new angles makes the strength “stick.”

• Builds muscular endurance – so your legs don’t just get strong, they stay strong over time.

• Balances weaknesses – lunges, step-ups, and unilateral movements correct imbalances heavy barbell lifts can hide.

• Improves real-world performance and stability

At times it might seem repetitive. But it’s one of the smartest, most intentional ways to get stronger, see more results/gains in the main lifts, get fitter, and be more resilient/reduce risk of injury.
