Look no further than this full-body dumbbell exercise that can send a burn through your entire body, build stronger muscles and develop core stability — it’s the dumbbell thruster.
Anytime this beast crops up during the best CrossFit workouts, it still gets a groan from me. But funnily enough, it’s one of my favorite dumbbell exercises to program. That’s because it’s an effective and efficient strength and conditioning tool — it hits every major muscle group, sends your heart rate soaring and burns calories. You can go heavy to prioritize strength or lift light for endurance conditioning.
Ready to give it a try? Here’s how to do the dumbbell thruster, the benefits and some variations to spice up your workouts.
Benefits of thrusters
The thruster is a compound exercise found in functional training. It targets various muscle groups and joints and mimics the natural movement patterns you’d find in daily life. Thrusters combine a squat and overhead press while challenging your core muscles to help stabilize your trunk as you lower down, then powerfully drive your ‘bells upward overhead.
Barbell thrusters are beneficial for loading much heavier than dumbbells but also increase the likelihood that your dominant side will take over and leave your weaker side not activating properly. For this reason, dumbbells are better at ironing out those potential imbalances, plus they’re more accessible for most people — especially if you’re unable to lift a barbell overhead.
Over time, thrusters develop power, endurance and strength. To begin with, I recommend using light weights, then add weights as you get stronger; you can’t protect your lower back if your muscles aren’t recruiting how they should.
How to do dumbbell thrusters
For the dumbbell thruster, I recommend a set of the best adjustable dumbbells. Hex dumbbells provide more stability on the floor, but a dependable set of adjustable dumbbells help you scale quickly during workouts if you program thrusters alongside other exercises.
- Start with feet hip or shoulder-width apart and rack your dumbbells onto your shoulders with both elbows slightly forward. Brace your core.
- Perform a squat, lowering until your thighs sit parallel to the floor, and keep your spine neutral and chest forward.
- Push your knees outward in line with your toes and keep the weight mid-foot to heel.
- Drive upward to stand and extend your hips as you press your dumbbells overhead.
- Push your head slightly through your arms and lock out at the top, contracting your body and keeping your biceps close to your ears.
- Begin to bend your knees and elbows as you lower your weights back to your shoulders with control and lower back into a squat with both weights racked.
- Keep the elbows lifted as you lower to catch the weights onto your shoulders.
In the overhead position, keep your back straight and avoid leaning forward, sending your arms wide, or extending into your lower back. The thruster requires existing shoulder flexibility and strength to shelve the weights overhead and control them back to your shoulders.
As well as trying barbell thrusters (during this variation, you’ll punch your head through and under the bar for extra stability in the overhead position), you could try single-arm thrusters if you want to benefit from unilateral exercise and hone in on one side of the body at a time or get used to the movement pattern with a lighter weight.
Thruster workout to try:
To get the most out of thrusters, include them as part of your workout programs. If your goal includes lifting at or close to your one-rep max, consider programming them as a standalone exercise and aim for 3-5 sets of 2-6 reps using a heavy set of weights.
If you’re adding thrusters into a workout, ditch the dumbbells for a moment — you only need one kettlebell and this 10-minute finisher to build a strong core and burn calories. Spoiler, thrusters are non-optional.
