They don't add extra charges for not being a member for snacks. You get free upgrades and get a special line for concessions. So worth it if you get concessions normally ever, not if you don't. I think they also have another tier up that gives you 3 movies/month but I have no idea what that costs.
$15/year is pretty reasonable for the perks for AMC. Most theater chains are trying to charge monthly for membership which is outrageous
What I did was make sure I had creatine daily, high protein at least 1g per lb. Lift heavy twice a week one day for upper body, one day for lower body. Go for reps other 2 gym days.
Everyone's body is different but that worked for me.
