Navy Seal Workout In honor of Veterans Day, we thought you might like to try a military workout! Former US Navy Seal Stew Smith writes about military fitness for Even members of the military don’t always have a lot of time to keep in tip-top shape. So Stew has an intense 20-30 minute workout for military and civilians alike. He recommends “supercycles” with no resting as a way to reach your goals without spending hours in the gym. Thank you to Stew, veterans and active duty U.S. military members for your sacrifice and service!
