You don’t need to invest in a gym membership to get fitter, stronger, and healthier. The American College of Sports Medicine reports that you can get a great home-based workout with the following inexpensive essentials: an uncluttered space of about 100 square feet, light dumbbells, a stability ball, and resistance bands. They recommend a training routine featuring 8 to 10 different exercises that works all muscle groups.
