This paper identifies and analyzes the major muscle groups engaged during the tennis backhand shot. Beginning with a definition of the action and the body parts involved at each phase — preparation, swing, impact, and follow-through — the paper systematically examines contributions from the legs, core, back, chest, shoulders, arms, forearms, wrists, and neck. It also addresses common injuries associated with the backhand, including tennis elbow, rotator cuff inflammation, calf tears, and tendonitis, and explains how poor technique amplifies injury risk. The paper concludes that virtually every major muscle group in the body works synergistically during this complex movement, underscoring the importance of proper form, stretching, and targeted strength training.
To understand what muscles are involved in a backhand shot, one must first define the actual action and the body parts engaged at each moment. Many consider it common knowledge that the elbow muscles play a role in a backhand swing, in part because the muscles and tendons of the elbow are frequently implicated in tennis elbow, a condition common among players. Since these muscles are directly involved in the backhand shot, they merit discussion. They include the forearm muscles that enable the wrist to bend back in preparation for a shot — known as the extensor muscles — which attach to the lateral epicondyle via a tendon.
During the backhand, the player positions themselves to prepare for the shot by tossing the ball with the right hand, then generates a forward motion from which they swing the racket, impact the ball, and follow through, landing with weight supported by the back leg and pelvis. This complex action involves multiple muscle groups working in coordination.
The muscles extensively used in the backhand shot include a wide range of groups across the entire body:
(1) The leg muscles, primarily the quadriceps at the front of the upper leg and the gluteus muscles, help stabilize the player throughout the shot. (2) The gastrocnemius muscles serve to stabilize the core during the backhanded motion. (3) The chest and upper body — including the pectoralis major and latissimus dorsi — provide power and support during the initial phases through the shot itself. (4) The deltoid muscles supply power to the racket arm during the shot, accompanied by the rotator cuff and shoulder adductors, which are responsible for generating force at impact. (5) The triceps help support the forearm and elbow throughout the swing. (6) The wrist and hand muscles actively engage during the swing phase of the shot. (7) The lower back supports the torso and stabilizes the body as the player follows through. (8) The abdominal muscles — including the rectus abdominis and the internal and external obliques — stabilize the body, position it for the backhand, and enable the player to drive the ball forward during the swing and follow-through phases (Walkerbout Health, 2007).
What many tennis players do not realize is that the neck muscles — including the neck flexors and extensors — also engage during the hit phase of the backhand shot and the follow-through (Walkerbout Health, 2007). While most people assume the arms and legs are the primary muscles engaged, it is clear that the entire body participates in this complex movement. For this reason, it is critical that all players warm up and prepare the affected muscles prior to vigorous play, in order to reduce the likelihood of sprains and strains to key muscle groups.
The rotator cuff and the muscles and tendons along the scapula are often inflamed and overloaded in players who frequently perform backhand shots. This occurs in part because the rotator cuff provides much of the power during the swing, impact, and follow-through phases. The forearm muscles are also commonly overused, though they are typically injured only when the player employs poor technique or form (Walkerbout Health, 2007). The potential for injury is significantly reduced when the player takes care to stretch properly and refine their stroke, thereby avoiding undue stress on the tissues surrounding these muscles.
The back is also commonly utilized as a source of stabilization and power during the backhand shot. Improper technique can lead to back strain, usually resulting from an overly arched back, which can cause small tears in the tissues supporting the spine (Walkerbout Health, 2007). Players who continuously engage in poor form are at greater risk for chronic injuries — even arthritis — if they do not adequately care for these muscles and commit to proper strengthening and conditioning between playing sessions (Walkerbout Health, 2007).

In short, one may conclude that nearly all the major muscles of the body are involved in the tennis backhand. The muscles of the lower and upper abdomen, the muscles of the upper and lower back, the gluteus, the quadriceps and calves, the forearms, deltoids, biceps, neck, and even pelvis are all involved in this shot. All of these muscles work synergistically to support the human body during a backhand swing. As with any sport, it is critical that the player pays close attention to their form and the force of their swing in order to protect the primary and supporting muscles that allow for proper postural functioning throughout the movement.
