Yes, but when you do weights, you want to do a certain muscle group one day, give them 72 hour rest, so for instance:
Monday: Cardio and weights for arms
Tuesday: Cardio and weights for legs
Basically, Cardio plus weights is great. Just don't do the weight training on the same muscle group everyday. The muscles need to have a rest period in between. Missy is a great one to talk to about this, she has a lot of experience.

Be ready for the twists, and the unexpected, because you know it will come and try to side track you. It's in those moments that your true character and commitment are tested, how you react is a great indication of how or if your life has truly changed. Brian ~ Biggest Loser Season 3
