Teach you a way to reduce thighs: lie on your back after running, first raise your leg at a 90-degree angle with the ground, retract one leg, and then change the other leg. Repeat 10- 15 minutes (the frequency does not need to be too fast). Reducing thighs is very effective, and many of my female members do so! ! Plus: you don't have to run every day, just three times a week! But supine kicking can be done every day, and it can also be done when you don't run before going to bed at night, because the intensity is not very strong and will not affect your sleep.
