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

An update on the review I left on Amazon last month. Note: I have NO financial arrangement with Bullworker of any kind. My first Bullworker was 1974. I also have a 2014 steel bow and a 2015 classic. Been using my X5Pro for three months (bought Feb. 2021) and find it more effective than ever. I have a basement full of exercise machines collected over 40 years and the X5 pro is now my go to strength conditioner.



On isometrics: Here are two facts. 1. The sun sets in the west. 2. Put a muscle under a certain amount of tension for a certain amount of time it will GET STRONGER! Isometrics work! In fact over my 50 years of training I find that isometrics, done correctly has been the QUICKEST WAY for me to get stronger compared to isotonic exercise.-free weights etc. I'm not saying it's the best way, it may or may not be, or it is the only way, but for absolute strength gains over a short period of time, nothing comes close. It also, at my advance age, has given me more muscular definition-just enough to notice. Strength gains tested (using the X5) against my isotonic equipment have been around 15% after 3 weeks of 2X a week 30 minute 40 different 10 second holds. My Amazon review explains the benefits of the X5 (two strap, 28 " size adjustable spring so I won't repeat.) With severe shoulder impingements, which keeps me from doing any reps, (your strength gains, proven by studies, come only with the 7/10 second holds), the X5 is a godsend, allowing me to keep my strength training going full bore. Note: I don't know anyone over 60 years old that doesn't have severe joint issues after years of using free weights. I'm not anti free weights, but if you use them, keep the intensity at a moderate level with correct form. In fact, one of the best overall free weight exercise you can do, the dead lift, is partly an isometric exercise. You lift the bar to you knees (isotonic) but then you hold it there-pure isometrics.



I've never had a problem centering the X5 when using just one strap on each side. Lower the thick fabric part to the bottom, grab the straps at around 90/100 lb. mark and you are good to go. Having the old steel bow and the old classic, makes my training even better. I use a strong spring in the Pro so I can use one strap at a time and not run out of resistance, and use a lesser spring in the steel bow for my pressing holds. There are good exercises for the legs on the Pro, but one of the best isometric leg exercises, is the ONE LEGGED LEG PRESS. Hold onto the 2 handles, put your leg on the outer strap, push out and hold for 20/30 seconds instead of just ten. VERY EFFECTIVE FOR LEG STRENGTH. This is best done on the classic, why? The classic is stronger than the pro, and take more pressure with it's steel cable, but this can be done on the X5 unless you have very strong legs.



To wrap up this review, the X5 pro is great for all ages. But here is an important Fact. When you get older, you need MORE exercise, not less. Almost all Gerontologist conclude that mortality and overall body strength are very closely connected. It does not have to be the Bullworker x5 Pro to accomplish this, but the X5 Pro is such an efficient, extremely effective and easy to use strength training device (example:don't risk joint injuries with free weights when older, nor you don't have to attach it to a door like resistance bands and worry about them snapping), The X5 may be one of the best buys you can make for your long term fitness and health.

I’ve purchased just about every Bullworker product over the years; a few days ago I finally yielded to temptation and ordered the X5 Pro… even though “I didn’t really need it”.



Did my first workout today and I am completely satisfied and happy with this new device. I don’t have tons of money to spend on indulgences, but maintaining my health is a priority for me.



I like everything about this model: the size, the action, the weight, the sturdiness, the looks and feel. The straps are comfortable for bare hands (though I often use gloves for extra pulling power). The non-slip end caps are genius; and the manual (a book in itself) has many new exercises. I did most of them today and got a “complete gym workout” right in my living room. Then I put the equipment away; it fits anywhere and no clutter added to the home.



If I lost all my other exercise equipment tomorrow, I would feel confident going forward with just this one compact device. Glad I took the plunge.

X5 PRO 28 I cannot believe the fitness benefits is has provided to me. the eaae of use and the compact size is perfect for in home and on the go exercise fitness.
