I read an article that proposed 150 minutes of ordinary activity or 70 minutes of strenuous activity throughout the week. I often go for runs or bicycle rides, paddle my board, jump rope or go for a long hike. One of my number one activities is swimming. It’s the ideal opening to target the whole body and cardiovascular system. An hour of swimming burns just about as many calories as running. However, it avoids the strenuous impact on bones and joints. Whenever the weather allows, I incorporate swimming into my usual workout routine. I change between swimming laps, treading water and going through a few types of aerobic movements in the shallow end. Whenever I swim laps, I make an effort to switch between the dog paddle, sidestroke, breaststroke and butterfly to keep it interesting and change up the style of motion. Each one concentrates on unique muscle groups and the water provides a gentle resistance. I’m using most of my muscle groups to propel my body through the water. I’ve seen that exercising in the water increases my heart rate, builds strength and endurance and tones my muscles. There are medical studies that claim that swimming can work to lower blood pressure and control blood sugar. Even when I’m sluggish, tired or dealing with injuries or concerns that make high-impact aerobic exercise difficult, I can enjoy a swim. This activity can even help to alleviate pain and expedite recovery. One of the main reasons I choose swimming for exercise is because of the calorie burn. It’s so great that the time goes by particularly fast and yet I can feel great about the number of calories I burned. I don’t even notice the exertion until I get out of the pool. Then I suddenly realize that my arms and legs are sore from the workout.
