One area I'm focusing on now is abs, and the online library of ab exercises is simply amazing - I can even access it on my smart phone while I'm at the gym. It's like having your own personal trainer.
Now, if you can afford a personal trainer, by all means hire one - they not only motivate but teach, and that's invaluable. But if you can't afford a trainer but are looking to change it up at the gym, look no further than the ACE GetFit exercise library. And thank me when you do!
