What is a Thruster Workout
Whether you do the Deadlift, an Air Squat, the Snatch or Thrusters, it is important to use the right technique and form when performing your CrossFit exercise. Otherwise, you are not getting all the benefits and there is more chance of injury. When looking at what is a thruster workout, most often, it starts with using just a barbell. Then as you perfect the movement you can add more weight or change the type of exercise used to get more out of it. Key is to keep your movements controlled and smooth. The whole exercise is a fluid and continuous motion not short and separate. Whether you are doing a Thruster CrossFit routine, or as part of another workout, having a CrossFit coach or trainer is the best way to get the movement and form correctly.
Here is a breakdown of what is a thruster workout;
- Hold your barbell with an overhand grip and stand so that your feet are shoulder-width apart and your hands are also at that distance.
- Hold your shoulders back and keep them down and your spine straight.
- Your knees should have a very slight bend, you should not lock them, and your feet go under the bar.
- Slowly raise the barbell so that it is above your shoulders or up to the collarbone and make sure your elbows are either facing forward or underneath.
- As you slowly lower your body down into a deep squat engage your core and push out your chest.
- Now if you have enough flexibility to do so, drop your glutes lower as though in a sitting position and turn your knees out a little for stability.
- Engage your core and press your heels and the outside of your feet down, bringing your elbows up swiftly and push quickly into a standing position.
- At this stage of a full thruster exercise, you push your heels to the floor, engage your glutes and push the bar overhead.
- As you straighten your arms push your head forwards so that your ears are before your biceps then return your head so it is in line with your arms.
- Slowly lower the barbell to collarbone height once more and repeat the movements for the next thruster.
What Muscles Do Thrusters Work
