Yes, is the short answer. You will get a great workout with a 12kg Kettlebell.
A 12kg might be a little heavy for some Women and youngsters who are just getting into strength training. Therefore, It may be suitable to perform squats and deadlifts but a little heavy for swings until a little more progression is made.
The 12kg competition kettlebell is ideal for most even if you are an experienced athlete. Increase the reps you can get and reduce your rest period to get the most out of it.
Yes, they are awesome for weight loss. In Kettlebell training you are performing compound exercises in a range of motions. This means you are working multiple muscle groups at once, therefore, increasing the intensity of the exercise and burning loads of calories!
The American Council on Exercise conducted a study that concluded the average person can burn 400 calories in just 20 minutes whilst doing a kettlebell workout!
That works out at 20 calories a minute! 4/5 times that of normal weightlifting and nearly twice that of running.
12kg Competition kettlebells are a great tool for the complete workout to increase muscle strength and burning fat!
