AMP: Marc Megna's 8-Week Aesthetics Meets Performance Trainer Phase 4, Day 48
Sprint work is important to a great physique. Build up your hamstrings and glutes while you torch some fat.
Time flies when you're having fun—or when you're pushing your cardio limits. Each of these sprints requires only 30 seconds of max effort and is followed by a full minute of rest, so don't slouch.
If you feel up to it, add another series to your cardio work today. Yes, it's a lot of work, but your body and mind are more than ready to take on greater challenges. These greater challenges will lead to increased adaptation and continuing gains.
