What exercises can I do to tighten my core? I don't want to lay on the ground and do crunches because I wont stick with it. I have tried several times and cant stick to it. So anything at the gym I can do that will work my core? By the way I am a 19 year old female.

Okay, i got home and realized that i have no idea how to do the homework. This is what i am given; how do i do it? Please include steps. Amplitude: 4.5 Period: 5pi/4 (five pi divided by four) Thanks!
