Good that you've learned this type of kung fu. You also need to do some push-ups to strengthen your muscles. Not just learning in the morning, but start at home, training, so that your reaction will be automatic. A long time ago, there was a man who came and asked a very famous teacher to teach him the sword art. Daytime, he made him work, so that he trained his muscles. Because he also trained common sense. So, nighttime, when he's least expected, the master always sneaked into his room and brandished the sword at him, so he never could sleep. That's the way he trained. You always have to be alert. It's not just in training only, but always quick reaction. The same with meditation, we must also do it regularly. Then when a situation comes, it's just automatically our energy is there, our power is there to protect us; not physical, but similar to that. Similar with kung fu physical reaction, there's a spiritual reaction inside. It's very good to exercise. Not for fighting, but it's good. Because we have some pent-up energy inside. So, if sometimes you wear socks for too long, it's also not good. Because the used energy has to be discarded through the feet.
