https://community.usms.org/swimming/f/open-water-training-and-technique/13161/treading-waterI am currently wanting to become a certified SCUBA diver. The issue that I have with this is the pre-qualifications in order to get the certification (treading water for 20 minutes and the 200yd swim.) I have no doubt that I will be able to pass the swimmingen-USTelligent Community 12https://community.usms.org/thread/205214?ContentTypeID=1Thu, 22 Nov 2018 07:56:47 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:34b50e79-a3ff-4e3c-9816-85e56b8464d4GlennLook up drown proofing. With minimal movement anyone can sustain themselves in the water for an extended length of time. Essentially while in a vertical position in the water, you lift your neck and take a good size breath. Then put your face back in the water. You will sink a few inches, but with air in your lungs you will also float back up to the water surface. when you do, lift your neck again and take another breath. You can skull a little when you take a breath if you wish. It takes minimal energy to do this and can be continued for a long time. it is taught as a survival technique to Navy Seals.<div style="clear:both;"></div>https://community.usms.org/thread/205197?ContentTypeID=1Wed, 21 Nov 2018 09:34:07 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:c3ff4718-e30e-49bb-a1fb-e8cc4edecb8aForceDJI think what you&#39;re describing with just (or mostly) your arm motions is probably your best bet. Generally, when I tread water I pretty much only use my arms. It might require larger, more-frequent strokes of your arms...but it should suffice. The biggest factor to be considered is your own body&#39;s buoyancy. Your percentage of body fat, and lean muscle will determine how bouyant you are. That can make it easier for one person to tread water, while another is nearly sinking. But if you&#39;re not accustomed to treading water for that length of time...you need to get to the pool and practice so that you can refine your treading technique. Dan<div style="clear:both;"></div>
