According to the New Testament Bible, Jesus expressed physical weakness in His human form many times. He was weak from fasting 40 days and 40 nights.

Read here in Matthew’s Gospel about Jesus’ weakness.

Jesus was also very weak after being whipped 39 times, not eating and being provoked for hours. He was too weak to carry His own cross and another man had to do it for Him.

However, He was not weak per se. He was strong spiritually and He would also have been somewhat robust or strong as a carpenter.
