Weight trainers don’t usually expend the amount of energy in training that endurance athletes do, so they don't have to be as acutely aware of the intake of carbohydrate required to fuel such effort. For example, a marathoner or triathlete may require 7 to 10 grams of carbohydrate per kilogram body weight per day (3 to 5 grams per pound). This is a lot of carbohydrates—equivalent to more than 32 slices of bread for a 150-pound athlete.
For every person who lifts weights these days, it seems there are two who have a podcast about it. There are more bodybuilding tips promising greater strength and muscle than ever before, and along with them a ton of confusion; one buffed-up Instagrammer says lifting heavy will get you swole, while a well-known fitness personality has claimed in recent years that two 30-minute workouts per week netted him 34 pounds of muscle in a month.
