What it lacks in elegance, this sandbag makes up for in utility. Because the nature of sand is to shift, get ready for a workout that tests your strength, balance, and patience.
For each circuit, the first move is with the bag, the second is body weight, and the third is a stretch. Perform circuits 1 and 2 six times each, focusing on form. For the third circuit, complete 10 rounds as fast as you can. The whole workout will take 45–60 minutes.
