“The plastic caps should be rectangular, instead of round because the Titan Fitness 10 lb aerobics bar can roll away from you if it is placed on an uneven surface.
However, the aerobics bar has helped me drop 9.6 lbs of excess body weight in 10 days by doing high-volume traditional barbell exercises with it, like rifle "PT" (physical training drills) that U.S. Marine Corps drill instructors use to make U.S. Marine Corps Recruits do in U.S. Marine Corps Recruit Training. This includes doing many sets of high volume repetitions (e.g., 50 or more) and static holds, like front raises, for many minutes without any rest interval.
I recommend buying it but be careful not to lay it down on an uneven surface to keep it from rolling away from you.”
