Last night while watching E News I learned about the latest celebrity workout trend; Kettlebells. The iron weighted balls are allegedly responsible for Geri Halliwell's recent physical transformation. The routine not only slimmed her down, but also gave her an amazing six pack. 

Many other fit celebrities including Jessica Biel, Jennifer Lopez and Matthew Mcconaughey also use kettlebells with their workouts. It's no wonder why this activity is popular among the busy stars, you can burn up to 1,500 calories in just one hour of vigorous kettlebell training. The workouts include many squats and swinging the ball above the head and side to side.

Women shouldn't use over 9-18 pound balls with this intense practice. Kettlebells are pricey ranging from $60-$400! I'd recommend visiting your local sporting good stores to look for the best price.

I found this instructional DVD "Get in the Best Shape of Your LIfe" (Complete Guide to Kettlebell Exercises and Training) that received a five star rating on amazon for $40.

A study by researchers at the Department of Kinesiology at Occidental College in Los Angeles found that balance balls do serve a purpose.  The study says crunches performed on a stability ball boosted activation, or flexing, of abdominal muscles by 24 to 38 percent over crunches done without a ball. Participants in the study were fitted with electromyographic equipment that registered heightened activity in upper and lower abs as well as in obliques.

If you don't already have a balance ball I highly recommend Gaiam's Anti-burst BalanceBall available for $30.

This is how to perform an ab crunch using your stability ball:
