Is there one piece swimming suit for guys that gives more coverage from the shouilders to the knees?
Consider a “shorty” wetsuit. If the water is cold you can go up in mils (thickness) or lower for warmer water. And a shorty will give you some support/compression. But most importantly, you are taking a big and very good step to improving your safety and health. I am inspired by you. I wish you all the best and thank you for re-affirming that instructors make a difference in the lives of others.
