Power pack , could you calculate total price sending it to Chile
with the power pack, I started with the 20-inch steel bow and following the 90-day transformation of the included workbook. I am on my fifth week and I already feel differently, I felt that my chest has increased a little which I consider a success. And am continuing my training. Thanks to you Bullworker.
So far so good with the power pack. I injured my right shoulder at the gym back in January under the "guidance" of one of their "trainers." My sports medicine dpt strongly recommended your products to assist with my rehab process.
Best regards, steve
While the Bullworker and Iso-Flow can be used as a stand alone exercise program, I integrate them with my Body weight, Band program. For instance, before doing a set of pushups, I will first do an isometric hold with the Bullworker Classic or Steel Bow. Before doing a set of chin ups, I will do an isometric hold with the Bullworker. Before doing Bodyweight rows, I will do an isometric hold with the Bullworker Classic or Steel Bow. If I max out on reps with, let's say my chinups, I will follow up with more reps for the lats using the Bullworker Classic. One thing that I have noticed since incorporating the Bullworker system is that my reps have increased in my Body weight exercises. I had reached a plateau or sticking point ( which happens in many programs ). Once I got my Bullworker and started using it, my strength and stamina did increase. I am 69 years old and try to workout 3 times a week with a 20 minute warm up followed by 1hour and 15 minutes of musculation exercise. I also appreciate the objective read that the Bullworker gives with the sliding gauge. While at times I use a kevlar strap for isometrics ( or even reps ), the Bullworker takes out the subjective "feel" and gives me a read for progress. Overall, the Bullworker system has proven itself over the years. I remember when a friend of mine bought me the Super X5 over 40 years ago because of injuring myself with weights and finding out I had an injured disc between C5 and C6 as well as a lower back injury. I did want to mention the quality of the guides - plasticized and spiral bound so that they stay open. It is this attention to detail in the small things that make the Bullworker system a quality system worth the investment.
I am 72 years old and have not liked exercising much. I love this system. I exercise every other day following along with one of their videos. I see real results after just a month. I highly recommend this system.
