I be not sure what happen to the instruction for many peoiple below , but we rack arrive within 2 day -lrb- I love Amazon Prime -rrb- and I build it last night in less than 30 minute . instruction be idiot simple -lrb- which be good for I ! -rrb- very clear , and all item be neatly package and lable -lrb- right and leave -rrb- . I use a 9\/16 ratchet and the supply allen wrnech and have everything button up very quickly and easily . I have to be honest , i continue to be blow away by the quality and construction of Bowflex equipment . we now have a pay of dumbell , and a Selectech Bench and I have be amaze at how solid and good look everything be . I be a reasonably serious weekend warrior , and at 275 pound , I be not gentle on anything -lrb- treadmill , eliptical , bench -rrb- . I be certain the Bowflex item we have add in the past few month will last a lifetime .
