What kind of machine?

AmbyrJayde

So I walk to and from work, but it seems the faster I get, the less walking I"m doing, which means less calories burned. So I am thinking about buying an exercise machine but I have no idea what type to get, any suggestions?
I guess I could just get a treadmill, but it seems like 45-60 min of walking to/from work would cover the walking potion
but srsly what do ya'll think?
