You're De-Stressing Between Sets
Chilling out between weight sets is one of the most common mistakes Bob spots at his boot camps and the gym. To increase strength, you need to do your second and third sets of 8 to 10 reps with slightly fatigued muscles. If you have enough time to vent to your workout partner, then your muscles have enough time to recover. Instead of taking a break, Bob suggests, take a brief "pause" that lasts for just 15 to 30 seconds. "Any more than that and you'll lose the benefit you gained from the previous set," he says.
