are the handles on this machine strong enough to do dips on..
If you weigh 200 or less- however they are not meant to do so.
can you do leg lifts from the waist down on the Body Solid Powerline Roman Chair/Hyperextension( Hold handles and elbows bent and have your legs straight then raise then towards your waist.) And also with bent knees. I did these in a gym and I`ll tell you my belly went down real fast. Can`t wait to hear back thanks in advance.
No-- the hyperextension/roman chair from Body Solid Powerline is for hyperextensions for you back or sit ups for abs- I think you are looking for a vertical knee raise machine--that is for leg raises both bent and raised--check our web page under abdominal machines---see VKR`s (vertical knee raise machines).
