I think that previous comments are great but I would like to add something. I think that 6 steps of protein synthesis from https://studyhippo.com/6-steps-of-protein-synthesis-flash-cards/ would be interesting to read in your case. There is a lot of information there so you could probably find something interesting for you.
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.
Yup. Agree with Karin again 🙂
Swim outlet is the place to go. They make swimsuits for men that are full coverage like a wet suit but made from swim material. Good prices too.
