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.

Similar Assertions

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.

86%

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.

86%

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.

After a long workout, drinking a sugary sports drink helps your muscles refill their energy stores much faster than not eating anything at all.

75%

After a really hard workout, eating a lot of carbs helps your muscles rebuild a special type of stored energy (macroglycogen) much better than eating fewer carbs.
