In recent years, wearing a weighted vest has become quite popular especially in functional medicine circles. I actually just purchased a weighted vest myself to wear around the house and to wear while running and doing strength training at home. There are several options out there but a good rule of thumb is to begin with a weighted vest that is about 5-10% of your body weight and work up slowly. This may mean investing (pun intended!) in several weighted vests or purchasing a vest you can add weight to (usually in 2 lb increments). I have recommended weighted vests to many patients including my own father who is working to increase bone density and prevent bone loss. Wearing a weighted vest is an efficient way to increase gains, primarily in the realm of fitness and physical performance.
