Working out in the evening helps your body use protein from food more effectively to repair and rebuild muscle overnight—almost 60% better than just resting.

When you eat protein after working out, your body uses it to help repair and rebuild the tough tissues in your muscles while you sleep — and exercising makes this process work even better.

For older guys who work out with weights, eating protein after exercise helps their body use it better overnight to repair and build muscle tissue while they sleep.

Lifting weights helps your muscles rebuild their internal support structure while you sleep by boosting protein production in the connective tissue inside the muscle.

Eating protein after working out only increases the building of connective tissue in muscles for about 4 hours - after that, the building rate goes back to normal.

If older guys work out in the evening and then eat protein before bed, their muscles use that protein better overnight to repair and grow — about 27-31% better than just eating protein alone.
