You probably picture using a set of two, one in each hand, when working out with dumbbell. As a strength and conditioning coach, I can tell you that there are just as many exercises you can do with one dumbbell as there are with two. You can effectively train your entire body using a single dumbbell.
There are five exercises you can do to strengthen your legs, hips, arms, shoulders and core. It’s important to pick a weight that’s manageable for you to do all the exercise reps with good form and read the detailed descriptions for each exercise. That means avoiding moving your body in ways that compensate for muscle fatigue or weakness in the area you’re trying to work, such as doing a bicep curl while swaying your back as you curl the weight up with momentum from your back muscles. This video shows you how to pick the right weight.
If you’re new to working out or just returning after a break, be sure to ease back into it. You can check out my series on how to reboot your workout for a safe and effective path back to fitness that makes training a fun part of your lifestyle. The dumbbell should be held with both hands at chest level.
If that isn’t possible, hold the inhale as you squat down to a level where your hips align slightly below your knees.
Push through your feet and return to a standing position.
Keep your weight in your feet, legs and hips.
If deep squatting is difficult, use a low chair or sturdy box as a base to squat down and gently sit on with each rep. Hold the dumbbell in your right hand at your side while you stand on your left leg.
Inhale and then hold the inhale as you hinge from your hips to bend over halfway while extending your right leg behind you so that your chest and back leg create a long line parallel to the floor.
Repeat on the opposite side
Keep a soft bend in both legs if the back of your leg is too tight. To help with balance, you can perform these without weight while holding the side of a wall. Take a plank position with your feet a little wider than hip distance apart to help counterbalance the weight and movement when you lift the dumbbell to make a rowing movement in one arm.
With your right hand, hold the dumbbell on the floor. Lift the weight by bending your elbow and hugging it against your rib cage as you exhale.
Lift your arm and return the weight to the floor while holding it in your hand.
After doing the reps on the right side, switch to the left side.
You can perform this exercise from a basic hands-and-knees position in which you’re on all fours. Stand with the dumbbell in your right hand, held up at shoulder height, lightly resting in your shoulder.
Put your left hand on your hip and step your left leg out to the left, with your right leg straight and bent like a half squat.
As you step back into a standing position, both feet point straight forward as you push off your left leg.
Inhale from standing, hold the inhale as you perform the lunge, then exhale as you push back to standing. Inhale and exhale as you push the weight overhead.
If you want to switch the dumbbell to the other hand, do all your reps on one side.
If the overhead press is too much, you can modify it by touching your feet and knees on the floor.
The goblet squat exercise requires you to hold the weight on each end at your chest.
Lift your arms and touch the weight to the floor on the side of your body.
Inhale and return to center, then exhale and repeat to the left side to strengthen your hips and core.
Because you’re alternating the movement side to side, instead of doing two sets of eight to 10 reps on each side, you’ll do one alternating set of 16 to 20 reps.
If your single dumbbell is too heavy for this exercise, don’t use it until you get stronger; instead, interlace your fingers in a double fist that you can tap to the floor.
Depending on your current fitness level and how these exercises feel, one round of this sequence should take about eight to 12 minutes to complete. Always remember to focus on form. If you want the best results, repeat this circuit two to three times per workout.
