Their are videos to help you out. Or you can do it at the Gym. Use light hand weights, and maybe a step, to tone up those soft spots. This will not only be cooler, but you can get great benefits. If you have access to a pool, you re in business.
Exercises done in the water are very effective, and easier than on dry ground.
See if your local pool holds classes. Or just swim to your heart s content. None should be profoundly different than with your normal workout. Don t, expect to be able to do your personal best, in the heat. Do, always workout where other people are accessible, should you need help.
