Hi Deb,
I've only been banded for 2 weeks, and I can't wait to hit the gym and start losing weight!
I've been reading a lot of articles about LIFTING WEIGHTS and doing CARDIO as a complete workout routine. An average person can loose around 50% more body fat if combining both weights and cardio.
Try adding the famous "muscle confusion" regiment to your work outs. You can continue doing the 30-40 min of cardio 5-6 days a week, but do at least 20 -30 min of weight training BEFORE hitting the treadmill.
Let me know how it goes, I'm sure you're gonna see amazing results and feel great about your weight loss!
I found this article about Weight lifting (101 =D), maybe it helps:
Overload: To build muscle, you need to use more resistance than your muscles are used to. This is important because the more you do, the more your body is capable of doing, so you should increase your workload to avoid plateaus. In plain language, this means you should be lifting enough weight that you can ONLY complete the desired number of reps. You should be able to finish your last rep with difficulty but also with good form.
Progression. To avoid plateaus (or adaptation), you need to increase your intensity regularly. You can do this by increasing the amount of weight lifted, changing your sets/reps, changing the exercises and changing the type of resistance. You can make these changes on a weekly or monthly basis.
Specificity. This principle means you should train for your goal. That means, if you want to increase your strength, your program should be designed around that goal (e.g., train with heavier weights closer to your 1 RM (1 rep max)). To lose weight, choose a variety of rep ranges to target different muscle fibers.
Rest and Recovery. Rest days are just as important as workout days. It is during these rest periods that your muscles grow and change, so make sure you're not working the same muscle groups 2 days in a row.
Before you get started on setting up your routine, keep a few key points in mind:
Always warm up before you start lifting weights. This helps get your muscles warm and prevent injury. You can warm up with light cardio or by doing a light set of each exercise before going to heavier weights.
Lift and lower your weights slowly. Don't use momentum to lift the weight. If you have to swing to get the weight up, chances are you're using too much weight.
Breathe. Don't hold your breath and make sure you're using full range of motion throughout the movement.
Stand up straight. Pay attention to your posture and engage your abs in every movement you're doing to keep your balance and protect your spine.
Good luck!
