Walking and strength training with kettlebells have become my absolute non-negotiables. If I could only do one as much as I like lifting I would choose walking. Hope I never have to make that choice because I love being strong!I'll be 58 this September. Hard to believe cuz I don't feel older. I contribute my overall good health to consistent smart strength training predominantly kettlebells mixed with body weight skills. But also use bands, and barbells. My mobility has served me well through the years. I trained classical ballet and other dance modalities from age 3 well into my 40s. Dance is one of my first true loves and now have time to bring dance classes back into my schedule since my children are all grown. As I age, I feel it is extremely important to continue weight training. I love my cast iron kbs the most. I will say when I first learned kettlebells back in 2007, I added walking to my physical training 3x a week. It made my body feel so much better. I think walking is underrated and highly recommend it to compliment your strength training.
