I so-elated !!
Very happy. Nice piece of kit. I had avoided the old bicep isolator for a while thinking is was a gimicky kit and served only to add clutter. But I took a leap and it paid off. I have found it to be a good supplement to bicep training both pronated and supernated curling. Especially alternating dumbbell curls which mean I can hit the weaker arm harder.The Senshi Isolator is well made and has pretty good padding. Also the edges are rounded nicly and is pretty sturdy. I'm a 52inch chest more muscular then overweight and find the strap to give plenty of adjustability so that I can keep my back straight and shoulders relaxed. Found other isolators to be restrictive because of poor strap ajustment and forces you to hunch up a bit which risks adding pressure to your traps and neck. As I say.. this isolator doesn't do that.Aluminium.. so light weight, easy to take to the gym and will last an age.

Good product
It is how I expected it. Does the job however, I’m not a fan on the condition that it arrived. It had some gunk stain on the side which wasn’t nice to see. But for what it’s used for it works fine

Three Stars
works as expected but a bit awkward to wear. kind of pointless to be honest just do concentration curls

Very good for the money
Great for bicep isolation, not to big and bulky the strap around your neck is easily adjustable however the pad for your neck is very thin and possibly won’t last too long.

Width.
The only downside to this item is it's width,my shoulders are quite wide so i found the position of my elbows kept popping out of frame...otherwise you can actually fell it target your biceps.
