Consider this arm workout a challenge: how many total reps can you do in 5 minutes?
Simply alternate between two exercises, doing 5 reps of each, while resting as little as needed for 5 minutes straight.
Each time you repeat the workout, try to do more reps.
It’s guaranteed to blast your arms in a hurry.
1. Hammer Curls
Stand holding a dumbbell in each hand, your palms facing in. Maintaining this grip, curl the weights to your shoulders. Keep your elbows tight to your sides throughout.
Do 5 reps then move straight to . . .
2. Overhead Triceps Extension
Stand holding a dumbbell in each hand, your arms raised, your elbows bent 90 degrees, the dumbbells behind your shoulder blades. Without moving your upper arm, straighten your elbows, lifting the dumbbells overhead.
Do five reps, rest as needed, then go back to the hammer curls. Remember: your goal is to crank out as many reps as possible in 5 minutes.
