Running every morning 1/2h with my dogs, and every other day biking, when stuck in traffic in my car (every day
) I do simple breathing exercize (abds and diaphragm) and muscle contractions (legs, arms ...)
No fat or alcohol minimum 3 weeks before deep dive ... but a lot after
Good physical condition is essential for the body and the mind !!! stuck on the bladdy M25 or at -180m
