Many people focus on building strength with exercise, but muscular endurance is just as important. While you need strong muscles to lift, push and pull things, endurance keeps muscles going for longer without fatigue and with less risk of injury—helpful when you’re carrying shopping bags across town or going for a long walk or hike.

One way to improve muscular endurance is to do workouts using lighter dumbbells for a higher number of repetitions and minimal rest, like the one I’ve created below.

You can do this arms workout with light weights as a standalone circuit or as a finisher. All you need is a pair of 3kg dumbbells like these ones from Amazon.

How to do the light weights arms workout

Do this workout as a circuit, completing 15-20 repetitions of each exercise one after the other taking as little rest as possible. That’s one round. Rest for 20 seconds, then start the next round, completing three rounds in total.

The moves:

Rainbow raise
Two-way raise
Dumb waiter to Y-raise
Triceps extension
Hammer curl to overhead press
Chest press to narrow press

Exercise guides

Lift the dumbbell over your head to the other shoulder.
Continue, moving the dumbbell from shoulder to shoulder.

2. Two-way raise

Stand with your feet hip-width apart, holding dumbbells in front of your thighs, with your palms facing you.
Keeping your torso still, raise your right arm in front of you to shoulder height and your left arm out to the left side to shoulder height.
Pause, then lower both with control.
Repeat but bring your left arm up in front of you and your right arm out to the right side.
Continue, alternating directions with each rep.

Stand with your feet hip-width apart, holding dumbbells.
Bend your elbows to 90° and tuck them into your waist, with your forearms pointing forward and palms facing up.
Keeping your elbows tucked to your waist, rotate your forearms so they point out to the sides, squeezing your shoulder blades together.
Extend both arms up and out to the sides, so you form a Y shape.
Reverse the movements to the start.
