Exercise Advice: Sit on the ground with your legs extended and spread apart. Hold a kettlebell in one hand and position it directly behind your head with your elbow in. Slowly raise the kettlebell up and extend your arm to the top position. Make sure to keep your elbow in a fixed position throughout the entire range of the movement to focus the tension on the triceps muscle. Slowly lower the kettlebell down to the starting position and repeat with the opposite arm.
