Having a 4 year old, a newborn on the way, and a military spouse.... it is near impossible for me to even consider a gym membership these days! My friend is a fitness coach and she recommended these to me. They go right on your door and there are so many options for how to use them! If you love to workout but cannot afford a gym membership or have a busy schedule, this is the way to go! Also, I would recommend a home pull up bar as well. Use both together and the results can be significant!
