Dear James,
My friend decided to join my gym so that she would have me to motivate and train her. She has never worked out once in her life. She's a couch potato. Lucky for her, she has a good metabolism.

While working on abdominals yesterday, I noticed she was having a really hard time with sit ups/crunches. She was trying to lift with her shoulders and kept moving her chin since her abs weren't strong enough to do a crunch. (I literally had to hold her chin and shoulders straight while she was crunching so that she wouldn't hurt her neck...she could only do maybe about 5) She tried the weighted ab machines and was ok with it. The problem is that those machines cause a bulky look which isn't so hot on a girl. I figured that hip flexor (leg lifts) exercises would be best but I only know 2 different kind of exercises. Plus, isn't that for lower abs only? Any recommendations on what to do? I guess I'll get her to do leg lifts until her abs are strong enough to do regular sit ups.
