JCK and whoever else is looking to lose weight Here is what you can do:
The plan is Circuit training:
1- the first step is that you want to pick around 10 exercises that work your shoulders, chest, upper (and lower) back, lower body and abdomen. So choose 2 exercises for each area I've mentioned. I've put some exercises that you can use. You don't have to use them if you already know other exercises. The point is to pick ones that work the areas I pointed out.
Example exercises for back: 1st video is a barbel row, 2nd video is a dead lift

example for chest: 1st video is a dumbbell press, second is an incline dumbbell press (you can do them with a barbell bar if you like)

2- for each excercise, you want to determine what your 1RM (1 repetition maximum) meaning the movement in which you can complete a single rep. Then you must ONLY lift for the above exercises about 50% to 60% of your 1RM. NO MORE THAN THAT. Example is say you can do a a a 1RM of 100 pounds for a bench press, then 50% of that is 50 pounds, so you would use that.
3- once you have chosen the exercises and determined the weight you will be lifting, it's time to start the workout. the plan is to go through the 10 exercises without a break in between. Do only 5 reps. So say you do a bench press, immediately do a barbel row after it, then a military press, then a leg rise, then a squat..etc. once you are done the 10 exercises you start over again. doing the entire exercises in a row like this is called circuit. You want to do about 3-4 circuits before you take a break or a few minutes. Obviously if your are breathing hard after doing one circuit take like 20-30 seconds break. Once you start this out 4 circuits is a good goal. After a few weeks of doing this you want to add more exercises to the circuits since you will be in better shape. The whole workout thing should not take more than half and hour to do. Don't do more. And don't jack up the weights.
spending time after that on the treadmill or a bike is not bad either (that is if you have any energy left)
hope it work for you.
NOTE: circuit training while it makes you lose weight, it also makes you gain a bit of muscle. So if you find yourself gaining a bit of weight after doing this for a few weeks, don't panic, it's just a bit of muscle that you have gained. You won't get Arnold like big muscles doing this, but it will make you look lean and fit.
hope it helps you.
