There are many thigh slimming exercises that you can do with a Bosu Ball.
Below are pictures and few tips for correct form.
Starting Position: Step on top of a Bosu Ball so that your feet are facing forwards and in a comfortable position. Hold dumbbells in your hands at your sides.
Form: Bend your knees and hips as if you were sitting in a chair. Keep going until your thighs are about parallel with the floor (90 degree angle at the hips) and hold for a brief second. Then, exhale and return to the starting position.
Personal Trainer Tips: During this exercise, it is important to keep good alignment of your ankles, knees, and hips. For many people, the knees have a tendency of caving in and the feet have the tendency for turning out.
It is much harder to squat on a Bosu ball, so use a comfortable range of motion.
Some people have a lot of difficulty standing on the soft side of the Bosu ball because of flat feet, really weak ankles, or other lower body postural problems or injuries.
If squats on the soft side are too challenging, try doing squats on the flat side of the Bosu ball.
If you have trouble squatting, you can also try building up your strength on a leg press machine. The leg press machine will also work all the major muscles in the lower body, and you can build up slowly on the leg press.
