Bests & Worsts Reviews from Amazon

I'm using it in lieu of traditional weight training and calisthenics. You might do this as well, or just use it as a primary means of generating muscle strength and endurance - it will absolutely work for you if you use it correctly. Using it with traditional resistance training will absolutely enhance your results. I am gripping it in the beginner's position and doing multiple sets of twelve reps. I have never used any other piece of exercise equipment that has been so effective so fast. I'm 58 years-old and have a lot of nagging joint injuries which keep me from exercising in more traditional ways. Particularly my left shoulder, which has bursitis - causes a very deep debilitating pain and limits mobility of the joint. This device, with attention to proper posture, allows me to exercise my upper body even with the shoulder issue. The shoulder problem keeps me from doing some of the exercises others might be able to with this device, but it doesn't matter. It's ripping my upper body like nothing I've ever used before. I have been using it for just over two weeks, with several days off in between intervals to allow time for my muscles to heal (these things take longer when you're older.) So realistically we're talking about 3-4 days of usage in total with 2-3 days in between for healing. And I can already see a large difference in posture, musculature and overall appearance. It is absolutely blasting my upper chest, lower pecs, lats, intercostals, biceps, triceps, upper abs, deltoids and frankly core muscles I have never felt before and didn't even know I had. It's incredibly effective. Last night someone I know asked me if I had started working out! Again - that's after 3-4 days total using this device. Unreal. **UPDATE** Been about a month I think... Still absolutely love this item. But there are a couple of things I think it important to mention. First, the metal does undergo fatigue from usage. And if the spring weakens under tension, it can break. Be aware about possible failure. I have worn out two of these already - one bent real quickly and I am returning it. This model has an inner safety spring, but if it snaps, it could cut your chest or face depending on where you're holding it when it goes. When. Not if. Second, because it weakens, it takes less and less pressure to bend the bar over time. So after a month, it's not the same unit you started on - it's easier because the spring is weakening. After two months, it's even more so. I have basically committed to buying a new one as needed. It's still cheaper than a gym membership and I am getting insane results. Went from 51" chest to 53". Upper arms are now 17.5" from 16" at start, and my shoulders are now 62 inches around which I don't have a starting measurement for, but I know I've grown. People are noticing and asking me if I work out. **EXTREMELY IMPORTANT** IT IS VERY VERY EASY TO INJURE YOURSELF WITH ONE OF THESE DEVICES I'm 58 years-old and I have been around the block a few times. So dig - this device will strengthen your muscles, but it will not do as much for your tendons and other connective tissues. So as you use this thing and start to gain, please resist the urge we all have for going up in difficulty - either by gripping narrower on this device, or by buying a stronger one. PROGRESS SLOWLY. You might think you're in peak condition and ready to jump up to a 60kg or 80kg power twister. Be very careful advancing in size with this thing. It's not your muscles you will injure, it's the tendons and ligaments and fascia attached to the muscles and bones that will suffer injury. And you might never fully recover from that depending upon how bad it is and where. I'm still using the widest grip but have gone from 8 to 12 and now to 24 repetitions. It's giving me tone in areas I never saw growth in before like neck and upper chest and my tris are the sickest they've ever been at this point. But I'm not going for SIZE with this device. Because from my experience - that's where I'm going to go one rep too many and too heavy and I'm injured in a deep tissue area - and at my age it would probably be game over. Could be for you as well. Be very careful - this thing will injure you in places that don't heal. So go for reps until you can do like 48, then slowly move up in resistance starting with 8 reps, then 12, etc. It's a long game, not quick muscle gain. This thing will rip you, but leave the gains in size to more traditional methods like machines or free weights. Why don't you see these in gyms anymore? Because they wear out and weaken and become dangerous to use, and because people who go too heavy on them tend to injure themselves. Don't progress to too heavy a bar - it's reps reps reps with this thing. Not resistance. It will tear your ligaments in ways you won't recover well from. Permanent damage. Trust me. After a few months of this thing you'll be stronger for sure and you might even get more benefit from free weights because your lesser muscle groups will be lit up. This thing builds core strength like nothing I have ever used. ANY PAIN stop immediately and see a doctor. Don't become a big fat used-to-be weight trainer like I am. Be smart.
