weight training 3 times a week. legs 1 day, arms and chest another day, and back and shoulders the last. i do a half-hour of cardio about 5 days a week. usually the elliptical or power walking.
lately i've been trying to mix it up with some short distance jogging and also the stationary bike.
looking to get into some yoga, and i wish i should fit more kayaking in, but since i dont have my own, it's a little tough.
sounds like you need to prep a little before you start your workout, have a healthy snack, and keep that water coming. make sure you're getting plenty of sleep.
my trainer recommends just what ratmist said...quick five minutes of cardio, then weight training, and then cardio.
good luck!
