The gold gym 20 lb adjustable weight vest takes intensity to the next level! It’s made of nylon, has 20 one pound sand bags that fit into pockets on the front and back of the vest to distribute weight evenly, padded shoulders, and has reflective tape for workouts at night. It has adjustable straps that snap together and offer a comfortable fit. It even has a little pocket for an MP3 player. This vest can be very effective for exercises like push-ups, pull-ups, squats, walking, and running. I’ve personally been using it for my long distance running, and it makes the workout much more effective. I’ve been using it for about six weeks and I already feel lighter on my feet, more agile and quick. For anyone that wants a little extra something to make their workouts that much more effective, this vest is a great addition.
