X5 Pro 28" Isometric Exercise Equipment, Portable Gym Trainer 0 to 150 lbs Variable Resistance, Upper Body Workout, Chest, Arms, Back, Shoulder & Abs Gear for Men & Women

Like having a gym in your hands! You can exercise biceps, triceps, shoulders, chest, abs, thighs, calves, and inner/outer upper leg muscles, and do it with smooth, safe motions. You can do one set of all of these in about 10 minutes, and I think most people would consider that all the muscle exercises they need to build and maintain muscle fitness.

I have 50 years of experience with isometrics. Bought my first Bullworker in 1974. They WORK. Put a muscle under a certain amount of tension over a certain amount of time and it WILL GET STRONGER-THAT IS A FACT! The X5 Pro with it's 4 straps (allows me to change the resistance and range of motion without changing the spring) a great feature. It's 28 inch size and changeable springs make the Pro very versatile. I have found that isometrics for me, can increase my strength quicker than any other method of training, and I've done them all. My cellar is full of strength machines. I use the X5 Pro differently than what Bullworker states one to do. I do 30-40 exercises with about a 10 second hold. I DO NOT do any reps. The strength benefits come wholly the the HOLD, and for me. the reps are a waste of time, I've tested this out over the years, and makes the workout too long. I only train 2 days a week. One big mistake is training to frequently with isometrics, which can strain your system without you knowing it. And yes, used correctly and faithfully the Bullworker CAN BUILD MUSCLE, it has for me. Also isometrics has shown to lower blood pressure and mine is 120/70, not bad for my age. The X5 Pro, used correctly, is a great tool for strength training and conditioning whether you are 15 or 80.

I am the type of person that has a really hard time with making it to the gym. I’m extremely busy and when I’m home I just want to be home. I was introduced to the x5 pro about a month ago and it has changed my viewpoint and my lifestyle completely. I use the x5 pro about 5 days out of the week and have seen a huge difference! My strength has increased, my mobility has increased, I look a lot more toned, and I’m able to do everything at home. The workout book that comes with it helps so much and has given me a complete at home workout. I canceled my gym membership and will keep to this. Thank you so much for introducing this to me!

The best workout is the one you'll do. I can get a very good workout sitting on the sofa watching sports or whatnot with this tool. I do go to the gym for cardio and stretching but I do about 100% of my resistance work with Bullworker products. A few hints - warm up. Maybe grab an ISO-BOW and do some of the warm up routines you can find on their YT channel. Less if definitely more, start with the easy spring. Take your time working up the spring progression. Breath and pay attention to posture and positioning. It really doesn't take a ton of effort to get good results. Another bonus - you can break down the X5 and fit it into a standard suitcase for travel. TSA might get concerned about large metal tubes and spiral metal springs, but they'll pass inspection.

I had an old Bullworker and decided to modernize to the X5 Pro. The old one was 36” long. The shorter 28 inch version works better for my stature. The old one had a single fixed spring, whereas the X5 Pro has a selection of springs to add or vary resistance depending on the exercise. The Resistance load can be adjusted from 20lbs resistance to 150 lbs of resistance. The ability to adjust the resistance load is a game changer for me. The old one seemed a little heavier, but the X5 Pro seems solid. Obviously, the X5 Pro is highly portable, and comes with a durable sling shoulder bag. It is like having a portable gym for you to use any time. As far as ease of use, the springs are variable to adjust to your ability level. The X5 Pro is a piece of equipment that I will be using for a long time, While there are other cheaper options available, I still say as an all around piece of equipment, it is a great value for the money. It has been a couple of weeks since it arrived, and I am already noticing the difference. It comes with a nice spiral bound booklet that shows how to use it and the many exercises that can be done. There are many online videos that are great resources to show a variety of exercises also

I had one of these when I was 13. Seriously. It was the original model but it was not much different. I was looking for some home equipment and saw this online and immediately bought this one and a Steel Bow. If you don’t think it will work for you at first - the muscle aches will convince you it does work.

Best isometric tool on market expensive I get it but it's high quality tool. I. Have owned and used them forever serious exercise product.

Very light - yet useful when traveling.

Excelente calidad, variedad de ejercicios, resistencia ótima para cualquier ejercicio.

A perfect quality training instrument. Very flexible due to various springs included.

Aprés avoir hésité sur la bonne taille de bullworker ( 51 cm pour le steel bow, 71 cm pour le X5 pro et 91 cm pour le classic) et consulté de nombreux avis en anglais sur le net j'ai choisi le X5 pro pour sa taille idéale pour moi ( je fais 1m70) et l'amplitude de mouvements que permettent les 2 sangles de chaque côté. Sur le site américain Bullworker ce modèle est même plus cher que le "classic" alors qu'il est au même prix sur Amazon. Pour moi c'est le choix idéal. Très bon outil pour pratiquer des exercices isométriques et qualité de fabrication extraordinaire. Après avoir enregistré mon produit chez Bullworker le service après vente m'a même proposé depuis les USA une rencontre en ligne pour avoir mon avis.

Excellent
