I'm of the opinion that if you're seriously interested in making fitness a lifestyle, you've got to think of it as an investment. So either buy/save for a real olympic barbell set or join a gym.
A one-off Golds or any other brand of fitness center with proprietary weight sizes is, in my opinion, a poor place to put any additional money. I know you already have one, but don't put any more $ into it. My Dad invested in a kit like that when I was a kid, and once I was past about age 17 it was worthless for anything other than very light bench press. There are exceptions, but in my experience, most of that type of fitness equipment quickly becomes useless if you're serious about fitness.
Most cities these days have gyms, and if you're lucky enough to live in or near medium to large cities, you can find one of several different chain gyms that offer very cheap memberships. Fitness 19 is the cheapest I've ever heard of @ ~ $15/month, but even Bally Total Fitness, Golds, and 24-Hour Fitness usually have some reasonable plans available, especially if you're willing to forego coming in at peak hours. I haven't checked out the YMCA lately, but back in the day they were a good option too.
Here's what I would do if I were you:
- Continue to maintain a caloric deficit (AKA eat less fuel than you use).
- Join a gym. If you can't afford a gym membership, then:
- Buy a door-mount pullup bar or find a tree branch or some playground equipment with bars that can serve as a pullup bar. Playgrounds often have parallel bars too which are awesome for dips.
- Do Crossfit bodyweight workouts
http://crossfitnz.typepad.com/CrossFitBodyweightWorkoutResourcev2.0.pdf, and/or the exercises therein individually: pushups, pullups, air squats, burpees, etc.
- Run, walk, bike, or swim for pure cardio.
- Save your money.
- Join a gym when you have enough money.
If you can't do a pullup, do jumping pullups. If you can't do pushups, do modified (on your knees) pushups. There are scaled version of every Crossfit exercise I know of. For people interested in general fitness who have no equipment, there's no better way to work out than the bodyweight exercises detailed in that PDF I linked.
Once you have a gym membership or a proper home gym I would suggest doing one of 3 programs:
1) Starting Strength (

2) Stronglifts 5x5 (

3) Scaled Crossfit Workouts (

I haven't read the Fat Loss sticky in a while so I'm probably repeating a lot of what's already been said, but yeah. I'm bored at work.
EDIT: if you have an olympic bar, you're awesome and continue to buy weights for it. I thought what you may have had was some pile of trash like I had when I was a kid.
