weight lifting......any experts out there that can help me?

The best thing to build your muscle so you'll burn fat and get stronger is to work your muscles to fatigue. Try to find a weight that allows you to easily get up to say, 20 reps, but gets harder as you go along and by 20 you can barely do anymore. Once that becomes easier, you can do more reps or go heavier, or switch it up and go back and forth between the two.

I lift 5, 8, and 10 lb dumbbells and like to lift differently each time. One day, I may do 2 sets of 12 reps and the next week I may do 3 reps of 10 and then the next 2 sets of 15 and go back and forth. I've read a lot recently that this is great for your muscles because it confuses them and they won't get used to it like they would if you were just doing 2 reps of 12 each time you lifted, and this allows your muscles to keep adapting, growing, and getting stronger. :happy: It's working great for me so far. I can feel I'm getting stronger. When I first incorporated the 10s about a month ago, I could barely lift them with just one arm, and now it's getting easier.

you want to choose about 8-10 exercises, which comes out to about one exercise per muscle group. The list below offers some examples:
Chest: bench press, chest press machine, pushups, pec deck machine
Back: one-armed row, seated row machine, back extensions, lat pulldowns
Shoulders: overhead press, lateral raise, front raise
Biceps: bicep curls, hammer curls, concentration curls
Triceps: tricep extensions, dips, kickbacks
Quadriceps: Squats, lunges, leg extension and leg press machines
Hamstrings: deadlifts, lunges, leg curl machine
Abs: crunches, reverse crunches, oblique twists, pelvic tilts

Sequence of Exercises
Make sure you choose at least one exercise for each major muscle group.
The muscles to work include: Chest, back, shoulders, biceps, triceps, quadriceps, hamstrings, calves and abdominal's.
If you work your biceps you need to work triceps.. chest and back.. ect..
The easiest way to determine how much weight you should use on each lift is to guess (not very scientific, huh?):
Pick up a light weight and do a warm up set of the exercise of your choice, aiming for about 10 to 16 repetitions.
For set 2, increase your weight by 5 or more pounds and perform your goal number of repetitions. If you can do more than your desired number of reps, heavy up again for your 3rd set.
In general, you should be lifting enough weight that you can ONLY do the desired reps. You should be struggling by the last rep, but still able to finish it with good form.
It may take awhile to find the right amount of weight for each exercise.
In general, you can use heavier weights with larger muscle groups such as chest, back and legs. You'll need smaller weights for the shoulders and arms.

I suggest you start with a lower weight then adjust as you go. I am of the no pain no gain theroy.. but alot of people don't feel that way so only you can determine that. You do need to feel it burn after about 6 or 7 reps. The last two should be felt. Once you can get to 15 reps add more weight. Track your progress..

Before giving you specific recommendations, I'd ask that you read this article I posted in my MFP blog:

After you've done that... if you have questions, please ask.
