5'7" one scale saiid 155lbs the other said 164lbs either way its too much
willing to do 20 pull-ups/push ups, 10+ squates, willing to run,don't know about the wall, the gym just moved locations so its under construction still, they have the weights and cardio stuff.
Ok, I don't know your age, but if you want to lose weight healthily, you'd need to eat about 1500-1800 calories a day to lose a pound a week (1800 if you think you'd be active enough to sweat, 1500 if you are doing less intensive workouts.) When I say healthy, 2 pounds is the max you should be willing to lose a week (otherwise some people have the reaction when they lose all the weight they wanted... to gain all of that back with a vengeance.) Try to strive for ~600 calories over 3 meals and look for meals that are particularly nutritious. A meal and drink can easily touch 600+ if you aren't careful. You might need to research meals and look at the back of the label to see how much calorie and nutrients are in the food.
This means high protein/nutrients but low calorie.
Some people can go crazy with push ups, pulls ups, and squats (but they use nothing but their own weight.) You might end up bulking a bit, but not as fast as someone who does weighted training to bulk. There many varied form to exercising doing the pull up and push-up (each targeting a slightly different area of the muscles.)
There are other body exercises that you can research that targets other muscles more (the back, the abs, the sides, etc.) I tend to do hyper-extensions and crunches using the same equipment as the hyper-extensions for the lower back and abs
I love hitting the gym. Mine are though to gain muscles/weight than to lose weight.
Since obviously you'd be doing more cardio than resistance exercises remember to do HIIT.

You can also do resistance exercises aimed at losing fat. Believe it or not doing weight training (even it the exercises are aimed at gaining muscles) helps lose more fat than one realizes. A good article I would recommend is
this.
Also it's a good idea to separate a time in your day to hit the gym and hit the gym at this particular time as if it was a religious practice.
All good points,
Weighted training for endurance also works to burn fat even though it can end up adding some muscle over time. (you can think of some women doing 10 pound dumbbells 20-30 times each per arm.)
The gym I go to is crowded around 6-8am, 12-2pm, and 6-8pm. If you are adverse to crowds, prpl, I'd avoid those times, but you'd need to check out the times for your gym as your place might be slightly different with the times.
