The Muscles Used During a Snatch Exercise
The snatch is a power lifting exercise that requires you to quickly and forcefully pull a barbell from the floor to over the head all in one movement. It's an explosive exercise that gets your heart rate up and works several muscles throughout your upper and lower body.
The gluteus maximus is the largest of the three gluteal muscles and is the primary mover of hip extension. This muscle works during the initial pull of the bar off the floor and again during the final step of the exercise as you extend your hips to stand to the fully erect position.
The hamstrings are a group of muscles on the back of the thigh that consist of the semimembranosus, semitendinosus and biceps femoris. These muscles work together to stabilize and flex the knees and aid hip extension. During a snatch, the hamstrings are used to flex your knees as you squat down to the bar, and slightly used to re-flex the knees during the "scoop" phase and again during the "catch" phase. The hamstrings also work constantly throughout the exercise to stabilize your knee joints. Finally, these muscles work together with the gluteus maximus to extend the hips during the initial pull and the final stand.
The quadriceps muscles are worked intensely during the snatch to extend and stabilize the knees. The vastus lateralis, vastus intermedius, vastus medialis and rectus femoris make up the quads and are used during the initial pull, the catch and the final standing movement of the snatch exercise to extend the knees.
The gastrocnemius and soleus muscles of the calves are used to plantar flex the foot. This movement occurs during the second pull of the snatch when you forcefully jump upward and lift your heels off the floor.
Trapezius and Deltoids
The trapezius and deltoids are the primary upper body muscles used during a snatch. These muscles are used during the initial pull of the snatch to stabilize the shoulders and shoulder blades. The trapezius is used again during the second pull phase to shrug the shoulders upward. The deltoids and trapezius work together to pull your body under the bar and then to catch and stabilize the bar overhead.
