The way we're trained at Synergy Kettlebell Training involves mixing up the workout to learn different things about kettlebell training and your heart rate is always up. You get your cardio and your weight training all in 45 minutes or less.
I am never bored and constantly challenged. Kettlebell workouts are efficient because I find I don't have to do a lot of other workouts other than the 3 a week I do at Synergy Kettlebell Training. -Loukia M.
