Power Twister Bar-Arm,Shoulder Builder Spring Exercise, Chest and Bicep Blaster

This thing definitely works your muscles! Might be small and simple but does shape your muscles and makes you stronger.

This thing is much beefier than I expected. Be ready for a fight. Good workout

I really enjoy working out with these devices. Great for an old dude like me who is past all the hassle of going to the gymn or having lots of weights lying around. Great way to tone the chedt snd auxiliary arm and shoulder muscles.

I bought the light resistance for warm-ups. It seems to do the job pretty well. I wish it was just a little longer, though, which is the only reason for giving it 4 stars instead of 5. I have a more heavy-duty version from another manufacturer that is longer (by about an additional 9 inches) and I think the extra length is better for providing additional leverage.

this small size flex bar packs a punch to which i mean it will work out your arms and chest till they hurt but be careful it can get away from you if you are just starting out

I ordered the 20 resistance level. Elbow hurts when I use . This thing is useless to me but missed return date.

I’m currently unable to go to the gym due to a cast on my foot...so I am doing my own modifications on working out. I purchased this to add to my home gym. It is a bit harder to use than I thought it would be....BUT....I will work up to it!!!!! It is really good quality and I’m sure I’ll be using it for years to come!!!

I bought the 40 Kilo model and I have not lifted regularly in a year and currently I don't have much trouble making an 8 rep set for holding it static for 30 seconds or more. If you want a reference I'm 6' and should weigh 210ish. If I stay with it every third day I'm not sure how useful it will be in about 6 weeks. That said it is a spring which will inevitably wear out and it's cheap. Useful for if you can't get to the gym or as A shock exercise if your progress has stalled. Try to cancel out momentum for best effect.
