New year, New Gym, New Workouts

I've signed up for 12 personal training sessions, and after 4 sessions, I think it was definitely worth the money. It seems I've got 32% body fat (not good) and my lower body is weaker than the top. My trainer has got me doing kickboxing, squats, ab work, TRX (really interesting) and loads of cardio which I hate but a necessity. After each training I feel like my legs are about to fall off, and yesterday my arms were shaking after a sparring session. 

It's torture, but just goes to show I haven't been pushing myself enough. I've seen 50-something women doing qigong/taichi, lifting weights, walking, running and they have ramrod straight backs and toned muscles. It's possible to keep our bones and muscles strong as we get older, but we've got to put in the work. There is no magic pill or slimming course that'll make us fit and healthy. We don't have to go for hours-long workouts, just consistent activity everyday. It's better than paying loads of money for cholesterol, diabetes, calcium and all sorts of pills for ailments which could have been prevented if only we looked after ourselves from a younger age.
