Thank you for responding Hallowed! I just finished reading that thread you gave me thank you. I see you also like single leg RDL's- I think they are great.
Actually, I am already doing most of the exercises suggested in that thread- I am following all the recommendations of
"Dispelling the Glute Myth"
by Bret Contreras
where he says
"... In order, the hip hyperextension exercises with the highest glute activation are the single leg bent leg reverse hyper (122%), hip thrust (119%), pendulum quadruped hip extension (112%), bent leg reverse hyper (111%)...."
pendulum quadruped hip extension = butt blaster machine
I have attached Bret's photo of a "tougher" looking version of this machine, but it is basically the same thing.
so I really want to keep using this machine but I am still wondering why it seems to be working my quads more than my butt (I do focus on squeezing my butt)????
