@zahrafit.cpt: Behind-the-back internal and external rotations using a PVC pipe are excellent for improving shoulder mobility and strengthening the rotator cuff muscles. This exercise targets the muscles and tendons responsible for shoulder stability and flexibility, which are essential for daily movements and athletic performance. Variations with resistance bands or cloth provide a more controlled stretch and activation, making them suitable for different fitness levels. Consistent practice can improve range of motion and assist with behind-the-back hand reaches, making activities like putting on a jacket or reaching for items easier. Aim to perform these rotations 3-4 times per week, with 2-3 sets of 10-15 reps. #ShoulderMobility #RotatorCuffStrength #FunctionalFitness #ShoulderHealth #FlexibilityTraining #Mobility #PersonalTraining #Gym #Fitness
