Great Addition to my Home Gym

Good Look, Lighter, Highly Functional

The X5 Pro is an excellent Bullworker. I have used Bullworkers for almost 60 years. It is smooth, easy to change springs, lighter weight, and functions exactly way a Bullworker should. I will be using this one for the rest of my life.

Easy to use

Easy to use. More convenient than old X5. But still use classic steel bow and iso bow

I had the original Bullworker when I was 17 in 1973 and I loved it back then. However the Bullworker X5 Pro is much more advanced especially with the 5 springs of tensions, in which I received with the ISO-FLO and ISO-Bow 10 days ago. I workout everyday and I have been able to incorporate these Bullworker products into my routines by replacing some of my exercises in way where I actually have been able to have better recovery time. I've always been a fan of isometrics. But, after watching several f Chrisman's videos I realized I can combine isometric with isotonic by doing the reps after the isometric hold and for 3-4 sets now. I also find that I enjoy doing the bullwor:er product exercise more than the others I've been doing before I got these products. As far as results; in only 10 days, I see strength increases in the lower and upper body and the core. I really didn't expect to get results that quickly. I started with yellow spring and now using grey spring. Little by little I've been incorporating the Bullowrker with the ISO-BOW and ISO-FLO. I really recommend these products for any exercise level or age. Quite flexible.

I used the lighter spring as the video shows, but the straps allow my muscles to be worked better. I don't know if it's just because the smoothness is better and the recoil is reduced. I'm definitely liking this model over the S3 by a medium amount. I say that because that's the difference in recoil and smoothness the X5 has over the classic. However, it's a smaller difference coming from the steel, as my video described, which shows that the steel is smoother than the classic.



I highly recommend people get the X5 if they haven't; well, wait for deals to get the best price like I did. I waited two months and paid $180. The X5 is a game changer.



I also notice compression changes, as my video shows. I didn't think Bullworker could make the S3 smoother with less recoil. I even made a post about this, saying they had to make it digital for the next model. I was wrong; having the X5 now proves me wrong since they did reduce the recoil and make it smoother
