Hi @tove, welcome to Mayo Clinic Connect. Congrats on running 2-3 miles most days. Strength training is an important part of an overall fitness program. When I added strength training, I found it made the running easier. And there are additional benefits for bones and muscles as well, especially as we age.

Here's an article from Mayo Clinic that explains what strength training can do for you — and how to get started.

I like doing simple exercises that use my own body weight and don't require extra equipment or going to the gym, like pushups, squats and triceps pushup, and things like that. I'm also trying to do better by adding more stretching into my day.

Do you have any stretching tips to share?

I also do strength training 2 days per week
