I have a fight coming up in 5 weeks, and i was wondering what the best way to prepare would be, such as my diet and fitness

i already train 6 out of 7 days a week

monday - thai boxing
tuesday - mma
wednesday - thai boxing
thursday - rest
friday - mma and circuit
saturday - mma and circuit
sunday - BJJ and mma sparring

any advice will be appreciated

thanks
