💠 Exercise guide
The Skier with Gymstick is inspired by the motion of actual skiing and places special emphasis on the triceps. This exercise simultaneously targets muscular strength, body balance, and movement coordination.
💠 How to perform the exercise
💠 Setup:
✅ Stand with your feet hip-width apart, knees slightly bent.
✅ Place the Gymstick under your feet and hold both ends in your hands.
✅ Lean your torso slightly forward with a straight spine and keep your elbows close to your body.
💠 Execution:
✅ As you lower the Gymstick, extend your arms backward from the shoulder joint, keeping your elbows straight.
✅ At the end of the movement, hold the contraction in your triceps.
✅ Then return to the starting position with control.
✅ Keep your torso and legs stable and controlled throughout the entire movement.
💠 Coaching Tips:
✔ Focus on triceps contraction rather than simply swinging your arms.
✔ Extend your elbows as much as possible without locking them completely.
✔ Keep your spine straight and avoid excessive bending.
✔ Exhale as you extend your arms, and inhale as you return.
💠 Benefits of the Exercise:
🔹 Strengthens the triceps:
This exercise specifically targets the triceps, fully engaging them in a way similar to cable triceps pushdowns, but with greater freedom of movement.
🔹 Body coordination and core control:
Due to the forward-leaning position and the need for stability, the core muscles are activated to maintain balance, enhancing neuromuscular coordination.
🔹 A suitable alternative to machine-based training:
For those without access to a gym or looking for a portable, low-cost option, this Gymstick exercise is an ideal choice.
🔹 Natural and functional movement pattern:
Inspired by the skiing motion, this exercise is performed dynamically and functionally, helping improve overall physical performance—especially in sports like running, swimming, or rowing.
💠 Muscles engaged in the movement
In this exercise, the triceps act as the primary movers. Meanwhile, the posterior deltoid and latissimus dorsi assist in controlling the range of motion and maintaining the force path. The core and spinal muscles also play a supportive role in stabilizing the body in the bent-over position.
