There's also walking which is like weightlifting for your legs. I got a dog after my dad passed away. I've been taking her with my elderly mother for 3km 50 minute walks everyday for over a year now. The exercise has helped my mother lose 20+ lbs and the conversation, sunshine and contact witn nature has helped with mood as well. I do go to the gym to lift weights, but while it grows muscles also increases my overall appetite and body mass. Not really sure if that's a net benefit for my heart, probably not. Intuitivly Maintaining extra weight is probably not healthy for you even if it's muscle, beyond a certain point. But walking is free and fun, and humans have been doing it a lot more for all our existence
