hello everyone, i have been training for a long time but recently started to follow the instructions of people on here. im doing lowerback/abs tommorow, it will be the first day to ever spend 45-60minutes on just those. my question is what should i be doing? all i can come up with is a bunch of dead lifts (5sets) with longer breaks inbetween and another back exercise used on an ab machine (dont know name). i guess my question is, what else should i do other than dead lifts? and what style dead lifts should i do?
