This is very, very good advice. I’m 5’5’’, 120 pounds.
It really doesn’t take that much exercise, and you don’t need to do high impact.
A half hour every day doing something that you enjoy will do wonders for you in terms of fitness.
That’s the most important point, enjoy the exercise.
There are those of us who like our exercise hard and intensive, where when we’re done, we are flat on our backs and just plain out of it.
Then there are those of us who need something far less intensive, but still gets results to keep motivated.
Whichever works for you, as long as you’re motivated to get out and do it again.
