Juan M. Carrillo 5 This is the second Bullworker I purchased, as a present for my wife. This is by far the most effective and versatile piece of fitness equipment. It takes isometrics and dynamic tension and combines them to deliver effective and satisfying workouts. Great for building muscles, strengthening, burning fat and cardiovascular training. It is built well and sturdy, so you will have this for many years to come. With basic care like wiping down after each workout and spraying a bit of oil on it, it will be your partner till the end. I currently hold outdoors fitness camps in Hyogo Prefecture. I will be buying about twelve more to introduce into my fitness camps. Your imagination is the limit with this. It also comes with a book that teaches different body part exercises. This is not a magic pill, you need dedication and hard work. You need to put the time and effort into your fitness journey to achieve your goals. With that in mind, I recommend this to anyone. In a time when everyone is being told to stay home, what better way to take back the control of your fitness by getting a Bullworker. Worth every yen. Fits in your car, on your shoulder, under your bed...everywhere for anytime.
