I've just got a second hand ab/back weight loaded bench for doing seated ab and back extentions. Just wondering if I should keep my powerline hyper-extention bench?, In someway does it work different muscles in the lower back?Thanks
I'd still keep it. Its a different excercise. And will help add variety.
Thank you for the input
Seated back extensions will do nothing for your glutes and hams - keep the hyperextension bench.
WOW, thats a very good point, didnt realize
And use it weighted as well.
