There seem to be a lot of misconceptions when it comes to working your muscles. The body is made up of so many muscles, somewhere upwards of 640, and so it does take significant effort to work each one. Of course they are not all equally important.
When it comes to the leg and thigh muscles, there are also so many. However, where we choose to focus could affect our balance and how our bodies protect themselves from injury.
There are several large muscles in our outer thighs, but because they tend to be bigger than the muscles in our butts and inner thighs, they compensate for a lot of the exercises we do. For example, although lunges should be working your inner thigh muscles and your butt, if those muscles are not strong enough to hold the position, or if the position is not done right, the outer thigh muscles compensate and cause a lot of tension in those muscles.
Before I blab on and on, the point I am trying to get across is that for the thigh muscles, we may need to do exercises that target individual parts of the thighs because these muscles are very important for balance.
Here is a video from LiveStrong that shows one exercise you can do to work the muscles in your inner thigh: Inner Thigh Lifts. These are difficult, but get easier as you do them more often.
As you do the exercise above, remember that your core is also the center of every exercise that you do, and it is the source of your balance. If you do not have a strong core, it is important that you work to build your core with every exercise. Keep your abs tight as you contract and relax your muscles and you'd be using your core strength as well.
Cheers Eights & Weights!
