Hold the ball and do small sideways jumps to train the psoas muscles
Stand with your legs together, holding a basketball or medicine ball in front of your chest with both hands. Bend your body forward and bend your knees, step your right foot out to the right, move your left leg up quickly, and at the same time turn your body to the right. When your right foot lands smoothly, the ball in both hands is also on the right side of your right foot;
After the left leg lands on the right leg, continue to step out to the left and land on the ground. The body also turns to the left, and the ball reaches the left side of the left leg. Do 8-10 times per group for each leg, 3 groups.
