So....I am a work out junkie. No I don't look like a fitness model and presently am working on getting my diet in check for the thousandth time but....I do really like the Iso 7. I train regularly with body weight doing the Convict Conditioning program along with Iron core fitness kettlebell program. I alternate between both usually. I saw the Iso 7 and decided there was a plane of fitness I had not ventured into but always wanted to... isometrics. Growing up my dad used it and called it dynamic tension. He just used his muscles with opposing tension. Since my purchase of the Iso 7 I have added it to my routine 2 days a week. So that's cc 2 times, Kb 2 times, and Iso 2 times a week. 6 workouts a week. Iso is great for working out in a pinch, and also for variety. I feel like I've gotten stronger since I've started using it. Is it the silver bullet? No. It is definitely a tool in my tool box I'm glad I have added. It is what you make of it....a tool is only good if used. I think iso 7 is a great addition to any home gym.Read full review

Although it is very well built and sturdy. I personally cannot recommend it. I have an old bulworker and was looking to replace it with this item..now the choice seemed right between this and a steel bullworker and really had nothing to do with the plrice..imam definetly not a weak person, just am evolving into the dynamic tension because of my martial arts..I could barely budge this to work out with...there is no tension adjustment with springs like the steel bullworker, so I have resorted to my old one until I can afford the steel one.

Much like Bully Xtreme. very stiff resistance. You must warm up before trying isotonics. very well made and as good a quality as the bullyxtreme for a fraction of the price. Useful to combine with calisthenics or take to weight room with you for added power in your lifts.

I use this at the end of my exercises it’s a good isometric exerciser. Some of the exercises on the chart are a little iffy. At first it’s a little hard to push the bar but as I continued to try it everyday I’ve made progress. Just don’t overdue it and Hurt yourself. There are a few videos online showing different exercises. Overall it’s a good product.

I have one of the originals but it is old and the instructions have worn out. I really needed the new instructions but wish there were on individual sheets - that's why the 4 instead of 5. Otherwise just fine.
