I purchase these to supplement my gym workout . I be very busy and some week I only get to gym 1 or 2 time per week . I also have a weekend home in the pocono that do not have a gym readily accessible . I have be use these for 2 week and they be very easy to use . the only issue I have with they be that it can be difficult to get clip onto correct ridge for weight selection but it be not overly annoying . the weight work well be balanced nicely and there be multiple way to hold they for various exercise . I have just purchase the bow flex weight bench to use with these because they be so nice that I would consider work out at home full time . another problem I have with these be try to find the weight plate to expand they to 90lb . I would appreciate if someone can send a link of where I can get they . enjoy these as they be really excellent
