Swimming/Running on rest days?
Greettings, I just started out doing the recommended routine regularly.
I was wondering if it would be sensible to go for an hour long swim or a shorter run on rest days in between? My swimming is somewhat extensive in distance and duration, but not necessairly very intense and feels more like cardio to me. Think breaststrokes/Backstrokes for 2 kilometers, not full speed crawl swimming.
I really enjoy doing it, which is rare for me and sports, so I would rather not give it up, but also want to do more calisthenics.
Edit: Sorry for the likely dumb question, I am rather new to anything other then swimming or basic cardio.
