1. Bodybuilding.com All Access Challenge Series

All Access Body Building Challenge

You don't have to look like a bodybuilder to win a Bodybuilding.com contest. The All Access Challenge Series pushes contestants to their limits as they try to achieve the most shocking transformations.

The contest has two winners: one male and one female. Both winners get a whopping $50,000 for becoming fitter than ever. In order to take home the grand prize, you have to show the most change from your before and after photo.

Even if you don't end up winning the entire contest, you're still eligible to win smaller prizes throughout its duration. Bodybuilding.com announces weekly contests and mini challenges on its Instagram account. These challenges have hundreds of winners every week, making Bodybuilding.com one of the best bodybuilding websites for prizes.

Any newbies to fitness should consider using free exercise and workout generators---these varied routines might increase your chances of winning!

2. Beachbody Challenge

Beachbody Challenge Weight Loss

With the Beachbody Challenge, you can enter for a chance to win $100,000 just for having an amazing beach body. Before you start the challenge, you'll have to purchase one of Team Beachbody's Challenge Packs. The Challenge Packs are fitness regimes that include a nutrition program, dietary supplements, as well as support from a fitness community.

Make sure you take a picture of yourself before beginning the regime. By the time you complete the Challenge Pack, you'll hopefully see stunning results.

Submit both your before and after photos, along with your old and new measurements to the Beachbody Challenge for a chance to win. You'll automatically receive a free T-shirt just for entering.

When you scope out the Challenge's homepage, you'll see dozens of entrants of all ages transform from out-of-shape to super fit. Eat right and build an exercise program that you can do anywhere to achieve the same results.

3. Healthy Wage

Healthy Wage Weight Loss Challenge

With Healthy Wage, you can place a bet on yourself. To start, click Calculate Prize on the home page to see how much you can win. Healthy Wage will ask you to input how much weight you want to lose, the amount of time you need to lose the weight, and how much money you're willing to bet on yourself.

The more weight you want to lose, the higher your cash prize goes. You can also earn more money by placing a higher bet on yourself. Although you'll have to pay to partake in this contest, it's worth it if you manage to lose the weight. At the end of the challenge, you have to film a video of your final weigh-in to earn your prize.

Healthy Wage also gives teams the option to lose weight together.

In the Next Team Challenge, teams of five can compete to lose the most weight. If you manage to keep your weight down after six months pass, Healthy Wage will return your entry fee.

The Next Team Challenge requires you to pay $25 per month if you're participating with a company, or $33 per month if you're not associated with one---either way, your team can win a $10,000 prize.

4. DietBet

DietBet Weight Loss Challenge

DietBet gives you the chance to split a pool of cash with other successful contestants. It's just like gambling, except you're betting on your own fitness. You must enter a bet into the pool each month to ensure that you won't go off track and fail to meet your goals.

In other words, you better get on a fitness program or download some free workout apps, otherwise, you might lose some cash.

You can choose from several different challenges on DietBet.

You'll see some games that have thousands of players, while others only have dozens. With more players, you'll likely have a shot at winning more cash (just keep in mind that you'll have to share it with other winners).

Each game has different goals as well---some invite you to lose 4% of your weight in four weeks, and some encourage a larger amount.

If you want to create a challenge among a group of friends and family, DietBet lets you do that too. Establish your own game and see who loses the most weight. Competing against your friends and family will only motivate you more.

5. Burn the Fat Challenge

Burn the Fat Weight Loss Challenge

Burn the Fat has several annual challenges. The challenges vary in duration---some occur over the span of seven weeks, while others run for just four weeks.

You'll notice that the challenges also have different conditions. For example, the Burn the Fat Love Your Body Challenge is based solely on the points you rack up for following your meal plan, completing challenges, and so on. If you finish the challenge, you'll get entered in a draw to win prizes.

The Burn the Fat Summer Challenge is based on the total transformation of your body. You have to submit photos of your body before and after the challenge, and also participate in weekly weigh-ins.

This huge event offers some of the best prizes---you might win a trip to a tropical island if you succeed!

The Summer Challenge has several categories of winners, such as best male and female overall, most ripped, and even most fit over age 50. It's both a fantastic fitness model competition, as well as a great way for the average person to lose weight.

Fitness Contests Pay Off in the End

Not only do fitness contests pay off physically, but they can pay off financially as well. Money is one of humanity's greatest source of motivation, making cash-prize competitions the best way to motivate yourself to lose weight.
