Exercise should be sustainable; therefore, it should be fun! I’d rather have you underdo it than overdo:  that is, we don’t want to feel sore after a workout; instead,  we want to feel “like we worked out”.

There’s a difference, and only YOU should decide what that level of intensity is right for you. I want to be able to do at age 90 what I do today.

Slow and steady wins the race!
