Wesley had average strength for a man his height and weight, although he was somewhat athletic due to the lifestyle he led. Although trained in the skills of a Watcher, his overwhelming fear initially prevented him from gaining experience in real-life combat, and rendered him useless in fights. However, as his personality hardened, Wesley gained experience during his time with Angel and became an incredibly skilled martial artist, as well as being proficient with weapons. He was able to take on vampires with success and subdued Justine Cooper single-handedly on two occasions. The best marksman with firearms in the Buffyverse, he is able to hit a tiny target while performing acrobatics (e.g. in episode "Inside Out", when he killed the demon Skip). His superior and detailed knowledge of demons and sorcery aided Angel and the team regularly.
