In weightlifting it’s about contractions with the muscles. Examples are: Tightening, squeezing, static holding and rarely locking out the arms.
In Ballet, it’s about the extension. Example: Locking out to a degree; lengthening, reaching; stretching outwards with the body long through the neck, arms, through the knees and ankles.
In weightlifting it’s about how many calluses you build on your hand – it’s a sign of respect and work ethics. In Ballet, it’s about how you carry your grace through your hands and how you group your fingers together in poise.
In weightlifting it’s about strapping your wrists tight for the most important lifts. In ballet, it’s about keeping the wrists flexible and allowing the wrist to go limp while you have graceful curvature of the fingers.
In weightlifting it’s about never rounding your back. In Ballet, it’s about rounding your back.
In weightlifting it’s about arching the back. In Ballet, it’s about the tailbone being tucked underneath for straight back alignment and not what textbook fitness call “happy cat.”
In weightlifting it’s about engaging your core. In Ballet, it’s about pulling “inward” through the center.
In weightlifting it’s about static stretching. In Ballet, it’s about a combination of stretching from dynamic and ballistic, while searching for angles that work best for you in stretching even if seems like you’re coming out of alignment within a single stretch (evidently with the know-how of not hurting yourself).
In weightlifting it’s about muscles being timed and under tension. In Ballet, it’s about moving your body as effortlessly as possible allowing the body to move freely with zero muscle tension.
In weightlifting it’s about muscle bellies. In Ballet, it’s about body lines.
Of course whether I explained things correctly or not isn’t what this entry’s about since these are my experiences and how I personally perceive them to be.
I hope you found my observations to be as interesting as I found it interesting to reflect.
