The fitness market was surprised by the revival of isometrics a few years ago. The protocol we tested called for preexhausting of the muscles by isometrics followed by slow body weight movements. The results were favorable. In a relatively short amount of time, once a week workouts produced gains. (See previous articles and data.)
The problem with isometric equipment has been that it has been costly to purchase equipment with a measuring device. Without a measuring device, the trainee has little feedback as to his effort. That problem may have been solved with the relatively inexpensive Igrip. (Retail less than $100.) The compact device measures the force applied pushing or pulling on the apparatus. If one chooses to use the device to preexhaust the muscles and then immediately follows up with pushups, chinups and dips, there is no reason that an effective upper body workout can not be achieved.
The 5 lb device has a capacity to measure forces between 0 and 200 lbs. The average range we saw in our tests were 14lbs to 48lbs so the device should have sufficient capacity for all but the strongest athletes. The IGrip has a built in timer that beeps when the time under tension is complete. The down side is that the device has no ability to exercise the lower body nor is there any way to automatically load the data into a computer.

Once again your review is spot on! Tested this device myself and followed timed static contraction with light weight movements.
ReplyDeleteGreat toning device plus I have gotten stronger. Best money I have spent on a fitness product.
I prefer the JymFit, I have tested both and found Igrip a little cheap compared to the Jymfit plus I could do squeeze and grip/wrist exercise with it.
ReplyDeleteIt is hard to beat the low price and convenience of these devices.
ReplyDeleteLove this site. Please do more reviews!
ReplyDeleteHello all..some details for you all... I had the original explosvie fitness tower and leg press with meter. Execellent devices and has helped my health a great deal. Had to get rid of them and was looking for replacements. But between the 1repgym and peakfit pro, i didnt have 5k to spend. Found the IGrip. Excellent device but only up to 200lbs. Saw JymFit. It went to 440 lbs. Got two of them and two of the static contraction belts here and looped the belt over the handles of the JymFits. I now have the best of all, cheap cost, can really put effort into the static movement, easily adjustable position, portable and all of it fits into a plastic grocery bag.

I am sorry but as good as the equipment is, the 5k price thats being asked is extremely ridiculous. If you can weld, you can build the same type of device for approx $500.
Hope this helps someone...Take care guys.
