Yea it kinda sucks that her gym is so limited. I agree with Sassy that she should drop the circuit training and go with body part splits. Maybe something like this.
Weight Training – 3x/week.
- Legs
- Back, Biceps & Core Work
- Chest, Shoulders & Triceps
Choose 3 exercises per body part, for 4 sets of 12.
For legs maybe she could include walking lunges, squats (even though she may not have a squat rack, she can take the bar from the bench press and squat with that with a spotter), Step up on aerobics bench with dumbbells (if she has no aerobics bench, she can use any other bench in the gym), straight leg dead lifts (again with the bar from the bench press), hamstring curls w/ stability ball (if there is 1).
For back and bicep, I think it's going to be hard for her to do without a few machines. But I think you said there's a universal gym, she could do some back work with that. Some other exercises could be chin ups or pull-ups (if there's a bar for that there), single arm dumbbell row, shrugs. For biceps hammer curls with dumbbells ,straight bar curls (or with dumbells), concentrated curls.
For chest maybe, bench press, isolateral dumbbell chest press (on stability ball if available), dumbbell fly,dumbbell decline bench press.
For triceps, tricep extensions, close grip bench press, bench dips, dumbbell kickbacks.
And for shoulders, shoulder press, side lateral raises, dumbbell front raises.
Hope this helps.
