If you've been noticing a lack of progress lately, what you've been doing in the gym probably isn't working anymore—so it's time to switch things up.

Grab a pair of dumbbells—you decide how heavy, but we recommend going slightly lighter than you'd expect—and challenge your shoulder muscles with this no-rest circuit. On the muscle-building menu: dumbbell squat-curl-presses, pushup renegade rows, and dumbbell squat punches.

Directions

You'll do this workout as a circuit, meaning you'll complete each exercise consecutively without rest. Once you've finished all exercises, rest for 30 to 60 seconds. Repeat the entire circuit for 5 to 10 rounds.

Depending upon your ability, you may shorten or lengthen the rest period. You may also complete more or fewer rounds.
