Hi Tommy, As far as recreational diving goes, the maximum limit from PADI (a top certification agency) is 130 feet once you pass your deep diving course. If you have an open water certification, you are certified for dives down to 60 feet.
1. Practice holding your breath for long periods of time when you're out of the water. Most swimmers need to hold their breath for about 20 to 30 seconds per 100 feet of underwater swimming. 2. Swim long distances underwater only if you're being watched by a friend or you're at a pool with a lifeguard. 3. Breathe in deeply, pushing the air down through your diaphragm and into your lungs.
