A trainer says this is the best workout you can do if you only have two dumbbells

If you have a set of lightweight, dusty dumbbells hiding in the corner of your garage or bedroom, it’s time you finally put them to good use.

"If you only have one pair of light to moderate dumbbells, the best workout format is going to be something higher-intensity, or focused on muscular endurance by doing high-rep sets," says ACE-certified PT Pioneer trainer Amanda Capritto.

She's put together this 20-minute AMRAP workout—a routine that challenges you to complete "as many reps and rounds as possible" of a circuit of exercises in a set amount of time. This format encourages you to work hard to get the reps in, challenging your muscles to build strength and endurance.

How to do Amanda Capritto’s dumbbell workout

• Dumbbell squat x10
• Dumbbell overhead press x10
• Dumbbell deadlift x10
• Dumbbell bent-over row x10
• Dumbbell lunge x5 on each leg
• Double biceps curl x10

Start a 20-minute timer then work through the exercises above as a circuit. Once you’ve completed all six moves, return to the beginning and start again. The aim is to complete as many rounds as possible before the clock hits zero.

"Though the goal is to complete as many rounds as you can in 20 minutes, it’s important not to neglect good technique for speed," Capritto adds. "Stay focused on your form, even if it means moving a bit slower. Rest as needed between sets."

This format auto-adjusts to suit all fitness levels. Experienced exercisers will be able to move through the circuit faster, while those newer to strength training can take things at a steadier pace. Both camps should finish the session breathing hard with their muscles burning—the only prerequisite of a successful AMRAP workout is that you push yourself.

Benefits of this workout

This workout is quick, straightforward and uses minimal equipment, helping you squeeze some mood-boosting movement into even the busiest of days.

"It trains all of the major functional movement patterns; squat, hinge, press, pull and lunge," says Capritto. This is a top way to train if you want carry-over to everyday activities(—daily acts like lunging down to tie up your shoelace or grabbing something from the top shelf at a supermarket will feel easy when you’re used to doing them with dumbbells.

"It’s a full-body workout that engages all of the major muscle groups and promotes all of the standard benefits of weight training," Capritto adds. "These are building strength, muscle growth, prevention of bone density loss and a healthier all-around musculoskeletal system.

"The workout also offers a cardiovascular stimulus, which is helpful for improving endurance, stamina and the health of the cardiorespiratory and cardiovascular systems."

Can you build muscle training at home?

It is possible to build muscle while exercising at home with minimal equipment, Capritto says. However, you need to train in a certain way to hit the stimuli needed to see results.

"Building muscle requires working a muscle to very high intensities," she says. "The most efficient way to accomplish this is by using heavy weights, but you can also perform more reps at lower weights, which is less efficient but doable."

She says beginners in particular can benefit from the latter approach as it allows them to train with minimal equipment, and being new to training means they will probably see faster results at first.

"If you’re just starting out, you don’t need to worry too much about using heavy weights, because your body will adapt to the new stimuli regardless. After several months to a year of weight training, you will likely notice that your muscle growth has stalled.

"You’ll need to increase the weights you use or otherwise introduce a new muscle-building stimulus to your workout plan, such as more reps or power-based movement. You also need to focus on eating enough protein and calories to drive muscle growth."
