Wow exceptional strength trainer. It definitely seems to be a pro product. I first seen this while doing physical therapy. I decided to buy it since the other hand grip trainers were to easy. The springs would end up snapping to easily. This is awesome. It comes with carrying pouch and 6 springs. I haven’t gotten past 2 springs depending on placement. It has notches where you can adjust the springs placement from easy to hard. Not sure how many pounds of pressure it takes but I believe I seen somewhere that it goes up to 500lbs. I’m no where near that. I would be nice to know where to place springs for what poundage but it doesn’t show you. Great product good luck maxing it out. Read more
