The first type of person I miss at the gym is the guy who spends his whole workout on his chest and arms and is deficient in all other body parts. I'm aware that a man's chest is a key selling point for most men but it isn't the only body part that women like, women also for some reason or another like butts. The next stereotypical person is the lady who spends her whole workout on the treadmill, stair master, and elliptical. I don't know how these ladies do it, because they look like they just aren't enjoying themselves. Seeing these people brought a smile to my face because it let me know that I'll get my strength back some time in the near future.
For all the people who are looking to add spice to their workout take a look at these two workouts and give one of them a shot. A little variety never hurts.
