The simplest way to make a workout you already do noticeably harder. This weighted vest carries 16 lbs of black iron sand distributed around the torso, which turns an ordinary walk into conditioning work and adds real difficulty to push-ups, squats, lunges, stair climbs and pull-ups. Nothing about your routine has to change the same loop around the neighbourhood and the same set of bodyweight exercises simply start demanding more from your legs, core and shoulders.Comfort comes down to how it is made. The shell is 2.5 mm neoprene, soft and breathable enough to wear over a t-shirt for a long session, and the stitching is fine and tight so the iron sand stays sealed inside instead of working its way out at the seams. Two adjustable buckles pull the vest snug to narrow and broader frames alike, and thick, wide shoulder straps spread the load so the weight rests on your shoulders rather than pressing into a narrow line.Details make it easy to live with. Reflective strips run along the outside so drivers can pick you out during an early morning run or a walk after sunset, and a back pocket takes a phone, keys and a card, which means no second bag bouncing along behind you. Runners, hikers, climbers and anyone chasing a first set of pull-ups can put it on, head out the door and get more from the time they were already going to spend moving.
