Many people look at an exercise regimen as boring, and most of them would be correct in their assumption. Walking on a treadmill, swimming laps, and lifting weights are all very repetitive. They offer little in the way of variance, and people who do not care for exercise see them as a mind-numbing block of wasted time. There are fun ways to exercise that will provide the same calorie burning and muscle strengthening they need, but they are more interesting than working out in the local gym.
Going the distance on a treadmill is often very time-consuming, but most people who use it are those just beginning to exercise for weight loss. It is often recommended for its low impact on muscles that need work, and it is a good way to avoid injuries. For those who have found it a boring way to go through life, taking a walk in the real world might help them realize exercise can be fun. Walking to the local park, ambling to the theater, and even stepping onto a nature trail are all more interesting than standing in a room with strangers on a treadmill.
Swimming laps is a great way to achieve overall muscle tone, and it can be an effective way to burn off calories. Going back and forth in a limited area might become oppressive, but swimming with friends in a pool, a local river or lake, or braving the ocean waves can be a better experience. The workout will be slightly different, but it could be the answer to getting those muscles worked while having some well-earned fun.
Lifting weights is a good way to tone muscles while burning calories, but the lack of variety can be difficult to take. Working the upper body muscles by rowing a boat or powering a kayak on a local river is much more fun to do, and it can give the same amount of work to those muscles while the scenery changes.
