Wobbly thighs can be a problem even if you are slim and relatively fit. Since women store fat deposits around their middle area -- such as the stomach, waist, buttocks and thighs -- the dreaded "thigh jiggle" tends to be more of a female concern. It is impossible to remove fat from specific areas of the body through diet or exercise. However, the right exercises -- when performed regularly -- can target the thigh muscles and help tone up your upper legs.
Do some form of aerobic exercise -- such as running, swimming or biking -- at least three times per week to burn off excess fat and give your upper legs definition. If you are new to exercising, start by walking for 10 minutes, and gradually increase the time by five-minute increments each session.
Take up in-line skating or wear ankle weights when walking. The extra weight at your ankles provides resistance that helps to strengthen and tone leg muscles.
Perform 10 squats, rest, and perform another 10 repetitions every day. Stand with your back against a wall with your legs slightly forward and one foot apart. Inhale and slide your back down the wall until your knees are bent almost at a 90-degree angle to the floor. As you exhale, slide your back up the wall to the starting position.
Perform two sets of 10 leg lifts daily. Lie on your right side on an exercise mat with your right elbow resting on the ground and your hand under your head. On an exhale, slowly lift your upper leg as high as you can in a scissor movement. Lower your leg as you inhale. Repeat on the left side.
Perform two sets of 10 leg extensions daily. Lie on your front with your legs fully extended on an exercise mat. Exhale and lift your right leg off the ground as high as it will go. Lower your leg on your out breath. Repeat the exercise on your left leg.
Wear thigh-shaping underwear for a quick-fix solution to wobbly upper legs.
