If you need additional rest, Movold suggests adding in an extra minute after completing the burpees. “For each move, focus on quality versus quantity, especially with the reverse lunge into curl,” Movold says. As for the dumbbells, pick a weight that allows you to perform each exercise properly for the full block of time. Dropping down to a lighter weight to put in a quality effort for the entire time is better than trying to use heavier weights and risking injury or early fatigue, Movold says. Using the appropriate weight will allow you to get in more reps without having to take unnecessary breaks and complete each exercise in a smooth, consistent movement.
