On his way out of the church, President Biden responded with three hops and a jump rope motion when asked how he was feeling after a bike fall.

According to the White House Pool Report as provided to PoliticusUSA:

At 4:58 p.m. President Biden exited church. 
Bystanders cheered as he was asked how he was feeling. He smiled, and took three hops forward, making a jump-rope motion with his hands. 
He got in his SUV moments later.
George W. Bush fell off of his bike and suffered a few nasty bruises when he was president. Nothing like that happened to Joe Biden, and it would not be unimaginable that Biden is in better physical shape than many of the Republicans criticizing him.
