Cottage cheese is high in a protien called Casein. It burns slower than whey and stays wit you longer. Its hard to gut down at times, so I personally, have to have fruit or raisins mixed in with it. A cup should be a good amout to take in. As for those classes, they can be hard especially spin. I have an ego block when it comes to the classes. I just don't feel its a guy thing. But, do some walking lunges with dumbells and you will change your mind real quick. Did arms today myself and 525 on ab reps. Still feeling stiff from the 300 workout. chime in!
