Another good one. I think burpees are a little more demanding considering you have to constantly stand up, fall down, pushup, repeat, repeat.
Bear crawl is demanding in seeing how far you can crawl trying to keep your back close to parallel to the ground. Both are great cardio exercises and full body exercise.
We use to cheat the exercise when coach wasn't looking and have more of a higher v shape to cover more ground LOL
