An indoor bicycle offers a low-impact method to slim down your thighs or bulk them up slightly, depending on your goals. It works with your overall fitness plan, which includes diet and other types of exercise. Spinning focuses most of the action on your thigh muscles, but it can help slim your entire body.
There's No Magic Thigh-Slimmer
If you're satisfied with your body except for your thighs, the calorie-burning power of a spinning workout can help you slim that area, but it might take some time -- it doesn't target your thighs for fat loss. You can't spot reduce, everyone's body is different, and you lose fat in different areas when you work out, according to the American Council on Exercise. And so the cardiovascular workout spinning provides helps you lose fat throughout your body, which will eventually eat away at those problem thighs as well.
Same Size, Only Better
As you lose fat in your thighs and gain muscle tone from the spinning workout, your thighs look more defined. Even if they are the same size they were before you started spinning, they appear more attractive and firm because of new muscle definition. Spinning works the front and back of your thighs -- the quadriceps and the hamstrings -- for a balanced look. It also uses the muscles in your calves and ankles, toning them as well.
Spinning Can Pump You Up
When you want to bulk up your thighs rather than slim them down, spinning offers a way to help. This won't replace heavy weightlifting, but it works as a complement to it. Ramp up the resistance on the pedals, making every turn difficult, for at least part of your workout. This extra resistance helps define muscle, while the cardio aspect continues to burn fat -- so the muscles you're creating become more visible.
The Spin on Spinning
Spinning every day without varying your routine is more likely to bulk up your thigh muscles rather than slim them down, according to the Fitness website. To keep them slim, stick to just a couple of spinning classes each week using low resistance levels. For fat-burning purposes, plan for 45-minute cardio sessions about four times per week, and sprinkle in some resistance training. When you reach your goal, 20-minute cardio sessions three times a week typically are sufficient.
