Query: Review for Kindle version

Although I've been into exercising and working out for years, I never really put much notice into stretching.I got this along withThe 5-Second Flat Belly Secret - Lose 2-3 Inches from Your Belly in Less Than 1 Monthfor Kindle in order to become more flexible and get a flatter waist area.I'm happy to say that after 5 weeks I'm way more flexible, my posture is a lot better, and my belly and waistline have become a lot more toned. This is a good buy.
