Im new here and just wanted to say I...I have a question ...I have been always been a runner, but due to me and my motorcyle hitting the road, I really cant run like i used to. So i took up lifting weights about 13 weights...I have really gained some muscle, suprisingly...However, i noticed i gained a little other weight, I have been doing all that a "lifter" is sopposed to, with protein, and eating etc. I started taking creatine, could that be whats making me feel heavier ? I do 15 minutes of the stair master 4 times a week before lifting, and run only 3 miles the other two days. I used to run 5 miles aday....I dont want to give up lifting I love it, can i do more cardio? Help?
