A friend suggested a trail mix with some greek yogurt before a workout? I read on Wiki it is nuts fruit and sometimes chocolate. So I guess the chocolate defeats the purpose so I am wondering what nuts or fruit others add? What nuts are healthy for you? I always thought they weren't that good for you!

i usually make my own ...you can't mix in honey any nuts from almonds to halzenuts etc...with a some dried fruits if you want to avoid chocolate ( so sometimes i like to add a dark chocolates in it ) the hen you roast everything in the oven and break it apart after

What sort of workouts do you do. Pre workout nutrition is definitely not needed for many workouts, depends on type, duration, intensity etc
