I think the bowflex would be a fine tool. No one should really be criticizing it unless they can max out all the rods in every exercise…
I have to admit though, 210, upgradable to 310 or 410, while nice, I wish it had a higher potential for adding rods. You add 100lbs by adding 2 50lb rods. So to get 410 up to 1010 would be pretty nice, but you’d need 12 more 50lb rods beyond the current maximum.
The ‘bowflex revolution’ seems like a better candidate for adding higher resistance, since it takes up less space. Look into it!
