I bought this programme for myself as a 50th birthday present. It's the best gift I've ever received and it's a gift that keeps giving. I'm not only fitter and faster, but more importantly, I'm less crash-prone. With better core strength, I can ride more stably and haven't had an major, even minor, crash. I can ride technical terrain that I didn't used to. As someone who doesn't like gyms, I've worked out at home and continue to do the programme after 2 yrs -- it's now part of my lifestyle as I believe it will take me into my older years without frailty and falls.
