I was reading some article here the other day (probbly either Berardi's or Barr's) and it strongly recommended a pre workout shake. What kind of shakes would you guys recommed? Carbs/protein ratio and total amount of calories? I tried about 20g of whey, 10g of maltodextrin and about 500g milk, so it was like 35g carbs and 35g protein, but I started feeling very tired and experienced some nausea during my workout. I'm guessing it had something to do with bloodsugar levels or something.
Any input would be appreciated.
