This is only a 10 minute workout but I guess you could repeat it or just elongate some of the steps/moves, right?
This is an 11 minute workout video but it seems fun and simple enough to get you back into exercising again!
Yoga Sun Salutations
I love sun salutations! It’s an easy way to warm up and even cool down. If you can’t stretch or do the pose to completion, do the best you can. Don’t overdo it! Sun salutations are an easy way to begin if you have never done yoga before.
