I have had these for about 4 weeks and have been using them mainly for benching, I have to say great bit of kit, I've added probably 4-reps to what was my 1 rep max. I have not been able to find these anywhere else in the UK, I have only seen US based people use them and wondered what difference they make. Well they defo do and well worth the money, I bought them on a special with £50 discount. Can't fault the service from Strength Shop either, they came within a day and half from ordering. Just about to start squatting with them, may drop another review once I see how that goes. Highly recommend for anyone looking to bump up their max strength.
