I got a session with a personal trainer in yesterday so I thought I'd share the info. Make sure you're doing strength training to build up muscle. Each pound of muscle you put on = more calories burnt at rest. Don't overwork your muscles and let them recover for 7 days. So do upper body only one day, legs another, and abs another while letting the other parts rest. Do strength before cardio and after a warm up. Eat breakfast within 30 min of waking up. It boosts your metabolism for the rest of the day. Your daily intake should be around 50% protein, 30% carbs, 20% good fat (omega 3, olive oil, etc). I just joined a gym after moving to Cali 2 months ago and I'm so excited! I've always wanted to take these classes, and it'll definately help me stay motivated. I'm not trying to lose weight, but it never hurts to be more toned.
