Yes, a banana and coffee work great for me. Now, I personally don't take BCAA's, pre-work PLAZMA, cyclodextrins, etc..... I have in the past tried these (or similar), but I transitioned to eating whole foods and cutting out all isolated supplements. You know what I found? I felt better, looked better, and saved a lot of money. I enjoy a cup of good quality coffee, ripe fruit (maybe a handful of raw nuts if needed), and it adds to the enjoyment of life. When I was slamming down artificially flavored raspberry pre-workout powder, it did not enhance my life in any way.
