I have to tell you...I did my homework AND I am a USMC Female Marine. This is the only exercise that burns fat, sculpts, keeps burning fat after your workout, and gets you ready for your 3 mile run without having to run nearly as much. I’m buying this for my home because it’s only this and my bench press that I need in my life to kick butt and be in deployment ready shape! Get this! Get some! And get going! PS If it’s this or some other whatever purchases you must have...get this, look good, and be be in great shape! GET SOME!!!
