Nearly hitting 40 years of age and looking to do some light workouts to keep everything working and start to use more muscles so that if I get to older age I'm in good shape. I'm not a gym bunny and to be honest I don't really want to be one but do want to exercise enough to get an all round workout.
Weekly plan in my head is:
3 x good walks
2/3 x HIIT spinning (25 mins a class)
and maybe buy some dumbbells and do 2 workouts a week with them
Is that a good enough use of muscles in the body between walking, spinning and weights or should I look to alter that rough plan? Any helpful tips very much appreciated
