I only practiced for a few days, but my body shape changed a little, and my waist and legs became smaller. Every time I jump before going to bed and take a bath at night, I jump for 30 minutes, covered in sweat, probably because I drank too much water a few hours before jumping! I didn't pay much attention to my diet either, but I ate less dinner than before. I'm still sticking to it, hoping to achieve my expected results.
