Help. :happysad: im new to this "keeping in shape" mumbo jumbo...so i need help. I never worked out before because, frankly i didnt need to (except for the health factor

h: ) Now that i'm out of HS and sitting on my ass because of not having a job...and i'm getting older...shits catching up to me. So before it gets out of hand, i want to do something about it.
My main issues are my legs, abs and glutes. Brett gave me a few ideas for abs...and i just tried the leg lifts and almost cried. I have a VERY bad back, and that hurt like a bitch!
All i want to do is tone. Any tips or ideas would be greatly appreciated...keeping in mind that i'm COMPLETELY out of shape and have a bad back.
