That's what the pounds say! I have lost 25 pounds in the past 3 months combining the Bellicon into my daily routine. It's fun, gives me energy, it's simple, and the routines can be changed up daily to keep it interesting. The product is extremely well made, durable and long lasting. Colors are variable, changeable, and fun! I have noticeably stronger legs and core, which is great for all things physical. I highly recommend the Bellicon re-bounder.
