I think Bruce Lee said it best: "Empty your mind and be formless. Shapeless, like water.” And I mean, Bruce Lee rules, so of course I do both yoga and meditation to achieve this mental state.
I have a yoga routine I do at the end of every workout. I use it as a way to stretch, cool down, and balance my mind and body after more strenuous exercises. I also regularly practice visualization techniques for my work. A clear and calm mind improves my performance during otherwise stressful and demanding jumps. Practicing meditation and visualization allows me to become efficient at getting my head in "the zone" before a jump.
I always start by visualizing a positive performance, then break down and visualize each particular set of tasks needed for a jump in three speeds: Fast, slow, and real-time.
Visualizing everything in hyperspeed helps me understand the flow of the jump. Visualizing again in slow motion allows me to see further details and work out any potential hiccups. Real-time prepares me for the actual jump by visualizing everything as realistically as possible.
Being relaxed and positive is the most important thing, and ultimately all this helps me chill and have a clear mind—like water. Thanks, Bruce Lee!
