Hi Nikirtehsuxlol. It depends on your goal but really if you want to lose weight you need to change your diet and keep the gym membership. I know me personally I work out a lot harder when people are around. Just as an example I was working back the other day at the gym. My back muscles (lats) are still sore partly because I really was cranking it with people around me and partly because a trainer there jumped in and spotted me at the end of a couple of sets.

Sometimes I will work out at home (with my weight set) or go to the apartment gym (small stripped down version of a real gym). Other days I bike the 5 miles each way to the church gym, workout, and bike home. Those are the days I usually feel the best because [A] I biked AND worked out in the gym and [B] I worked out hard because it wasn't just me in my house

In my case my ultimate goal is to do a minimum of one physical activity a day, and having options keeps it fun. I have been meaning to add going to the university pool to my regimen (its like a buck a day to get in) but just haven't gotten around to it yet.

If you want to do some physical activities at home but don't have any weights etc I would like to recommend researching video sites on the net. For example try this ab workout this lady does its killer (in a good way) the first time you do it:
