the iron ball
i have been using Russian kettlebells as part of my bjj strength and conditioning training for some time now and i must say the benefits are truly amazing. I have noticed a significant increase in my grip strength, my core strength, shoulder stability and that aching back has disappeared completely. A kettlebell can simply be described as an iron ball with a handle. Since being revived and introduced to the western world it has been the weapon of choice for all athletes and fitness enthusiasts seeking an alternative to the same boring workouts at the gym. They can be purchased from many online sites, are reasonably priced and last for ever.
