A great program that allows you to put in as much (or as little) effort as you think you have available. All movements have been a blessing for my stiff (aging, 53 years old) body, and I am (now 1.5 years into the programs) slowly regaining the flexibility (f.e. in my ankles and shoulders) that I still know from long long ago. Also my knee-aches that were present for over 25 years whenever doing high-impact stuff have been cured by doing the exercises that are focusing on getting more range of motion (extremely useful for my knees apparently) and strengthening not only the main muscle groups, but forcing you to use all those little balancing muscles and tendons, making all your joints 'healthier'. I can highly recommend Elements as the healthy basis, Vitamin/Mobius/Floor Loco to make moves interesting and flowing, and now since ~6 months also the Integral Strength program; a great follow up/complement to the Elements moves. Thanks a lot, keep up the good work! Emiel.
