Water, water, water! How nice is it that water can offer such intense and enjoyable workouts. To me, water aerobics is defined as a non-weight bearing (easy on the joints) resistance and aerobic exercise performed in shallow water. It has since evolved from just walking or jogging forward and backward in the water to jumping jacks and popular cross-country skiing movements.

Water equipment has also become more popular. Water weights, floating belts, and other useful equipment are used to increase water resistance as well as help with flotation and balance. Water aerobics can be performed just about anywhere; from health and fitness clubs to public or private swimming pools to even shallow lakes. All you really need is the motivation and dedication to splash around a little bit (warm weather wouldn’t hurt either).

Swimming is one of the best non-weight bearing activities out there and I totally recommend implementing a swim routine into your workout. It’s a great way to burn an enormous amount of calories all while having a blast in the water. Non-weight bearing refers to no weight or pressure being forced onto the joints, thus great for those with injuries, arthritis, or pain.

Although indoor pools are somewhat hard to come by, they are definitely worth the small cost to use. You may find indoor pools at your local health or fitness club, university, YMCA, or hotel. Before starting your swimming workouts, here are a few things you should know:

It can’t be easy making it all the way to the Biggest Loser ranch and then seven days later becoming the game’s first casualty, but James Crutchfield has embraced it. As the first eliminated contestant of the new Biggest Loser season nine, James weighed in as the second-heaviest player at an astonishing 485 pounds. It’s a weight he says shocked him, but he wasn’t surprised by it.

Voluntarily separating from his twin brother, John Crutchfield, due to the limitations of a knee injury, James went home and has done remarkably well for only having been at the ranch a few days. Down more than 75 pounds (since the September elimination), he’s proving that it’s entirely possible to lose this kind of weight on your own at home. “All I really needed was a jump start,” he says, continuing that “You don’t have to have surgery or take drastic measures” to lose the weight.

We spoke with James and asked about the concerns he had for himself and other contestants at the ranch do to their sizes, and he explained more about the swimming workouts that have allowed him to regain strength and mobility.

Moderate-to-high intensity exercise like jogging, swimming, or tennis may help reduce stroke risk in older men. But sorry ladies, for some reason the results don’t translate for women.

A study included almost 3,300 men and women in Manhattan, with an average age of 69. The men who did moderate-to-high intensity exercise were 63 percent less likely to have a stroke than people who didn’t exercise. Over a five year period, the baseline risk of ischemic stroke (the leading type of stroke) for all participants was 4.3 percent; 2.7 percent for those who did moderate-to-high intensity exercise and 4.6 percent for those who didn’t exercise.

I have a new client – a very lovely 40-year-old female who regularly appears on national TV. She has so many great qualities she can’t see because right now she is overpowered by her excessive weight, food choices, and lack of exercise. She was convinced I was going to give her a gym workout to follow and she dreaded the thought. Imagine her surprise when I asked her to tell me exercises she thought would be fun. She responded with “I never thought about fun.” Right there is the reason she is not active. Why would you move your body if it is not fun? How likely will you be to repeat it if you don’t get the feel-good benefit? Not likely. Is physical activity you despise nurturing? No way.
