The more you deplete your muscle energy stores during a hard bike ride, the more your muscles can overfill with energy afterward when you eat carbs.

Similar Assertions

If your muscles already have a lot of stored energy before you start exercising, they don’t store as much extra energy afterward—even if you eat lots of carbs.

92%

After a hard bike ride or run, eating lots of carbs for a few days almost always makes your muscles store more energy than before—even if the amount varies.

85%

After biking really hard and then eating a lot of carbs for a few days, your muscles store way more energy than they do after running hard and eating the same way.

83%

After a short, super-hard workout, your muscles refill their energy stores way faster than after a long, slow one—even if you eat the same amount of carbs.

80%

When you eat a higher percentage of your calories from carbs (like 80% vs 60%), your muscles store more energy after a hard bike ride—even if you’re eating the same total amount of carbs.
