well i went to the gym today and had hardly any energy which is strange considering i wasnt at school today due to suspension and i got more sleep and stuff. ive never been out of it like that and i hardly got a workout cause i like to have total body workouts every time. i only was able to work out my abs, arms, and i did a little HIIT. i could have worked out those areas even harder though normally. what can i do to prevent this. would anyone recommend an energy drink like red bull and if so when should i drink it.
