chest to bar pull ups -the standard is that the chest must come into contact with the bar at the top of the rep.
Double unders
Place the jump rope for the exercise behind your heels. Hold both ends of the rope in your two hands. Stand in a ready-to-skip position. ... Now take the rope swiftly over your head towards your front. Jump and let the rope pass beneath you.
kipping pull ups
A kipping pullup is when you use that momentum to create a “power swing” that drives your chin up and over the bar.
Clean + Jerk
Same as the clean and the power jerk but you can also split jerk.
