Hi, I am new to FAA. Is it OK to exercise? Do I have to increase amount of food in basic food plan? Say I walk/run for an hour 4 days a week and lift weights 3 days. Or would it be better to do lighter aerobics for half an hour and lift weights for 15 minutes, say only 4 days per week total? Would you recommend just doing light exercise or increasing amount of food? Thank you for any suggestions.
