As a student, I'm pretty broke. I wanted to join a gym, but couldn't justify the 20~30 pound per month fee. I decided to get these and started to work on a new routine.

With these weights, I can effectively do the following exercises:
Shoulders: Shoulder press; lateral raises; front raises; bent over raises; shrugs
Arms: Bicep curls; tricep extensions; tricep kickbacks
Legs: Dumbell squats; dumbell lunges
Chest' Flys
Back: Lawnmower (one arm) rows; bent over rows

I then combine these exercises with jogging around a lake by my house, and using monkey bars at the park for pull ups/chin ups, hanging leg raises, and do push ups and sit ups at home.

So I have cut out the middle-man (the gym) saving myself a lot of money. The dumbells have allowed me to focus on a lot of muscle groups that would be difficult to do using bodyweight-only exercises. They are made from metal with nice rubber-gripped handles. Not much more to say really. My only gripe is these little crappy plastic spinlocks that loosen a little after every set of exercises.
