I am a runner. I train for marathons,so I don't really do the gym. All I need is a good pair of running shoes and my iPod shuffle. Trail running is free! I recommend signing up for a local race.
Also,I recommend one of those 30 day squat challenges(Google them)Talk about WOW!
The muscle work you put in DOES show results. It lifts and tones quads and some leg.
