Today the time went up to 30s.

So 30s Regular Plank                         Not a problem

30s Reverse Plank on my elbows    That is the challenge but I do it for 30s

30s Right Side Plank                           Not a problem

30s Left Side Plank                             Not a problem

Yesterday I had problems with one of the elbows when doing the Side Plank but today both elbows were in pain 🙂
