After training one arm, both arms become easier to turn on—your brain can activate muscles with less effort, even in the arm you didn’t train.
Scientific Claim
Lower motor unit recruitment thresholds occur bilaterally after unilateral resistance training, indicating that both trained and untrained muscles become easier to activate by the nervous system.
Original Statement
“both sides exhibited lower MURTs (P < 0.001).”

Training one arm made both arms easier for the brain to turn on, even though only one arm was worked out — the brain got better at sending signals to both sides.
