What are some endurance and strength training you guys do with your WC?

Right now I just have an ab wheel and some push up bars. I have also tried doing my taiji and WC forms with ankle/wrist weights.

For endurance I usually do stance training, like sit in a low horse or cat stance for as long as I can. I also do some cardio drills every now and again, like jogging in place and then dropping down to do 10 push ups and then repeat.

What are some good exercises out there that you guys practice? Do you practice your wing chun while you work out (like forms or drills with wieghts)?

Its winter time and I want to stay in shape this winter. Too cold to go outside so I will be doing this stuff indoors. Also I am not looking to build mass, just strength and endurance.
