Kettlebells Review.

To get into shape for the movie "300," super-hunk-daddy Gerard Butler used a kettlebell workout!

In a world where fitness trends come and go (shake weight, anyone?), one can’t help but be suspicious of kettlebells. Since kettlebell enthusiasts claim you can get an amazing strength training AND cardio workout in just 20 minutes, it begs the question: Do kettlebells really measure up – or are they too good to be true?

The American Council of Exercise, with the help of research experts from the University of Wisconsin, La Crosse, recruited male and female volunteers that were experienced in kettlebell training. After establishing baselines using a treadmill workout, participants engaged in a 20-minute kettlebell snatch workout.

Here’s what researchers found: Aerobically, participants burned 272 calories in the 20 minute session, or 13.6 calories per minute. Anaerobically and aerobically combined, participants burned a total of 20.2 calories per minute – which, according to the lead researcher is “off the charts.” The incredible calorie burn occurs because the kettlebell snatch workout uses the entire body and is done in an interval-training format. In other words, you get a lot of bang for your buck.

In terms of heart rate, HR averaged 93% for participants. The VO2 max (often considered the best indicator of an athlete’s cardiovascular fitness and aerobic endurance), however, was 23% higher for the treadmill workout.

What does it all mean?

Researchers, based on the data and comparisons to previous research on weight training, concluded that the kettlebells can provide “one heck of a workout.” Beyond just building your muscles, the kettlebell snatch workout “easily meets industry recommendations for improving aerobic capacity.” In other words, it’s a very intense but efficient workout.

Especially with the busy holiday season upon us, kettlebells can provide a great cardio and strength-training program for people that don’t have a lot of time. Just make sure you work with an instructor, trainer or follow a DVD.
