Hey E-
That's sure a handsome little fellow with you in your photo - does he join you in your workouts?
I agree with Cheng on the supplementation. Are these boot camp workouts mostly strength or hardcore cardio? If you're doing killer cardio for more than 30 minutes (heart rate at 80% max) you'd benefit from the EFS Ultragen.
If you're doing a mix of strength, stretching, and minimal cardio you don't need it. Instead, focus on getting some energy into you an hour before you workout. I know some folks workout before breakfast but that's hard to do on an empty tank.
One thing I would definitely recommend is the Ultragen recovery drink (or protein drink of your choice). If you're working out hard you'll need a lot more protein and Moms especially need some supplementation. Make sure you take something within a half hour or less after your workout because your body is desperate for some fuel.
Keeping your bod fueled before and during workouts and supplementing afterwards will make you stronger and help avoid burning out.
One final thought, you said you want to lean down and lose some lbs. Focus on your bodyfat percentage rather than total body weight. Here's why, especially early on you might not see dramatic weight loss because you're actually replacing fat with muscle. You'll feel better, look better, but the scale might say you only lost 5lbs! The reality is that you dropped 10lbs of fat and added 5 of pure muscle so don't get too freaked over the scale.
Long post but wanted to wish you success.
