18. Forget about the scale. While you might think you want to lose "weight," what you really want to lose is fat. (It takes up much more space as muscle, so it's is the real culprit when your clothes feel tight.) But oftentimes, the fat you lose weighs less than the muscle you build. So it's entirely possible to slim down without shedding actual pounds. Don't let that discourage you from sticking with your new fitness routine. If your skinniest jeans fit better than they did before you began working out, you're right on track — regardless of the number on the scale.
Almost all major and small muscle groups are used to propel you through the water. Different strokes will use different muscles, effectively allowing you to target or use every single muscle in your body during a work out session, given you add variety to your set(s). Water is twelve times more dense than air. Propelling through the water acts as resistance exercise…which is the best way to build muscle tone and strength.
