FlexVest is a 2-in-1 patent-pending weighted vest with ankle weights that builds stamina, supports bone density, and burns calories anywhere. Load the vest with sandbags for resistance during workouts or walks. Includes two 5lb weights that strap to your ankles for leg day or balance work - or reattach to the vest for full weight. Wear the vest and ankle weights together for full resistance or remove the ankle weights to lighten the vest while keeping your workout going.
