I started an all inclusive fitness program (online) last year that offers exercise sets you can adapt to your current fitness/age ability. Exercise sets are trainer led. The program also offers yoga, mindfulness exercises and health driven nutrition, recipes, cookbook etc.. Weights are gradually added once you reach a certain level of fitness. The trainer insists you rest and use Epsom salts baths and restorative/ gradual stretching yoga the day or two following exercise to reduce muscle soreness and promote comfort. It has been life changing for me and I love it! I have never felt so good, I was 66 when I started and never exercised most of my life! My strength and flexibility has improved considerably!
