Before the first rep
How to set up
- 01
Set the rack. Put the bar at about armpit height and set the safeties a little below the lowest point of your squat. With light weight you can also clean the bar from the floor.
- 02
Grip. Hands just outside your shoulders with a full grip, thumbs wrapped. You need the whole hand on the bar to press, so most people skip the fingertip grip of a front squat and keep their fingers loosely around the bar.
- 03
Front rack. Step under, let the bar rest on the front of your shoulders against your throat, and lift your elbows forward so the bar sits on your shoulders, not in your hands. With a full grip your elbows usually sit a little lower than in a front squat, but keep them in front of the bar.
- 04
Unrack and stance. Brace, stand the bar up, take two or three short steps back, and set your feet about shoulder width with toes turned out slightly. Weight over your whole foot.
- 05
Brace. Take a big breath into your belly, pull your ribs down and tighten your trunk before the first rep.
Step by step
How to do the thruster
- 01
Squat. Keep your elbows up and chest tall and sit straight down between your heels, knees travelling forward and out over your toes.
- 02
Hit depth. Go down until your hip crease is below the top of your knee, or as deep as you can with a flat back and the bar still on your shoulders.
- 03
Drive up. Push your whole foot into the floor and stand up fast, leading with your chest and elbows so the bar rises straight up.
- 04
Press. As your hips reach full extension, keep the bar moving and press it straight up close to your face. Pull your chin back slightly so the bar clears it.
- 05
Lock out. Finish with straight elbows, the bar over your shoulders and midfoot, your head pushed through between your arms, and your ribs still down.
- 06
Lower into the next rep. Bring the bar back to your shoulders under control, lifting your elbows as it lands, and let your knees bend to absorb it as you go into the next squat. After the last rep, walk the bar back into the rack.

Common mistakes
Pressing before you stand up
Let your hip drive start the bar moving and only push with your arms as your hips reach full extension. Pressing out of the bottom turns it into a slow, weak press and loses the leg drive.
Pausing at the top of the squat
Stand and press in one movement. A stop in between throws away the momentum from your legs and makes the press much harder.
Elbows dropping in the squat
Lift your elbows as the bar lands on your shoulders and keep them up on the way down. If they sink, the bar rolls forward and your torso follows.
Leaning back and arching at lockout
Squeeze your glutes and keep your ribs down as you finish. If you still arch to get the bar up, the weight is too heavy.
Bar finishing in front of your head
Press straight up and push your head through at the top, so the bar locks out over your shoulders and midfoot.
Cutting depth as you tire
Keep every squat to the same depth. If fatigue shortens your reps, rest or lighten the load rather than half squatting.
Stay safe
Do heavier thrusters in a rack with the safeties set a little below the lowest point of your squat. If you miss in the squat, sit down below the safeties and let the bar settle onto them. If a press stalls, lower the bar back to your shoulders under control and rack it rather than leaning back to grind it up. If you ever lose the bar overhead, push it forward away from you and step back; only drop a bar on a platform with bumper plates and clear space. Thrusters are usually done for high reps, and form tends to break down with fatigue, so stop the set when your elbows drop, your depth shrinks or your lower back starts to arch. Stop if you feel sharp pain in your knees, back, shoulders or wrists, and get it checked by a qualified professional if it lasts.
Programming
Sets, reps and how much weight
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Strength | 3 to 5 | 3 to 5 | 80–88% 1RM | 2 to 4 min |
| Muscle | 3 to 4 | 6 to 10 | 65–78% 1RM | 2 to 3 min |
| Endurance | 3 to 5 | 12 to 20 | 40–55% 1RM | 1 to 2 min |
| Technique | 3 to 5 | 5 to 8 | 40–60% 1RM | 1 to 2 min |
Plan your next session
Put in a recent set. You get working weights for your goal, a warm-up and the plates to load.
Estimated 1RM 216 lb
Muscle sets
140–170lb
3 to 4 sets of 6 to 10 reps, 2 to 3 min rest. End the set when your elbows drop or the press slows down, not when your legs give out.
Warm up to 155 lb

Estimates use the Epley formula and work best from sets of 3 to 8 reps. Treat them as a starting point and adjust by how the first working set moves.
Questions
Thruster questions
What muscles does the thruster exercise work?
Mainly the quads and glutes in the squat, and the front shoulders and triceps in the press. Your upper back and trunk hold the bar in place and keep you rigid, and your traps help you lock out overhead.
How do you do a dumbbell thruster?
Hold a dumbbell on each shoulder with your palms facing in and elbows forward, squat to depth, then stand up fast and press both dumbbells overhead as your hips straighten. Lower them back to your shoulders as you go into the next squat.
How do you do a kettlebell thruster?
Hold the kettlebells in the rack position, handles in your palms, bells resting on the outside of your forearms and elbows tucked close to your ribs. Squat, drive up and press the bells overhead in one movement, keeping your wrists straight.
Is the thruster cardio or strength training?
It can be either. Heavy sets of 3 to 5 build strength, while lighter sets of 12 or more raise your heart rate fast, which is why thrusters show up so often in interval and conditioning workouts.
How heavy should my thrusters be?
Usually much lighter than your front squat, because your overhead press limits the weight. For conditioning, pick a load you can move for steady sets with clean depth and a full lockout.
Is a thruster just a front squat and a press?
Close, but the two parts are joined. The drive out of the squat carries straight into the press with no pause, so your legs help move the bar overhead.
