'Working out' and 'water' are two terms that you can easily find on the internet. But always with the word 'in' in between. Working out in water is good for your muscles without putting too much strain on the body. But did you know that you can also do a workout with water? That is: without getting wet. Working out with water can be done with an aqua bag, a Bulgarian aqua bag or an aqua punching bag, to name a few examples.
