should fit now. If not, move the deflate the ball and move it higher into the leg. Remember that your leg will compress as it squeezes over it. Throw a little baby powder on the leg, and you may want to shave the hair as well.
Next time you slide it on, get it as high as you can. After that find a dip bar, or anything that you can slide the straps on. Hang on it one side at at time to keep working it up. Also pull the straps up and squat as hard and deep as you can with no weight to let it ride up. I think you will be in good shape this run.
Also, anytime you might need a question quickly....feel free to pm me. I will get that a lot quicker.
