The gym can get painfully boring when you constantly follow the same routine each day. FitSugar reader plumeria9 has some great advice though. She says, "I try to use one new piece of equipment a week so I don't get stuck in a rut." There's a huge variety of cardio machines and weight lifting equipment, so every week, do something new. Once you've tried everything out at least once, you'll feel more comfortable alternating them into your routines. Not only is variety the spice of life, but doing the same thing over again can cause repetitive stress injuries. It also only works certain muscle groups, so by using different equipment, you'll end up working more parts of your body, becoming stronger and burning more calories.
