One technique Woltering regularly uses to reignite his training progress is focusing on sets of 3 and 5 reps, especially after he’s been doing higher-volume work. “They’re low enough to allow for heavyweights but high enough to still require an honest effort on every set,” Woltering explains.

This is especially useful at the beginning of your workouts before moving into higher-volume isolation work. Also, it can be an effective way to burn calories and maintain strength!
