Arousal that is too low costs you as much as nerves do. These pieces cover warm-ups, movement, and activation routines that bring your body up to the level the task needs.
Ultra-endurance swimmer Ross Edgley and Andrew Huberman explore the brain circuits and shifting psychological 'spokes' (purpose, shame, anger, love, money) that drive extreme endurance, drawing on mythology, neuroscience, and Edgley's record swims around Great Britain, Iceland, Loch Ness, and the Yukon River.
Physical activation supports resilience by engaging the neurobiological systems that sustain motivation during difficult tasks. The episode emphasizes perseverance through process, which aligns with using physical practices as a concrete anchor for mental discipline.

The article argues performers should train ambidexterity for symmetry, proprioception, brain plasticity, and possible creativity gains, citing skill transfer and cross-education effects. It addresses fears that ambidexterity signals brain damage, concluding adult training is safe and beneficial, then outlines drills from handwriting swaps to unilateral and contralateral exercises.
The Bioneer makes the case that very few people train their non-dominant side on purpose, and that this is a mistake: a fighter who can strike from both sides, a footballer who can kick with either foot, a dancer with full-body control. It cites the cross-education effect, where practising a skill with one hand carries some benefit to the other, and argues that the bigger payoff is the learning itself: a hard new motor problem demands concentration and constant error correction.

Move three everyday tasks to your other hand this week: brushing your teeth, eating, holding your phone. Then add one drill from your own sport or instrument on the weak side, done slowly and with full attention, for a few minutes every session.
Huberman explains how cardio, resistance training, and jumping improve brain health via arousal, osteocalcin, BDNF, lactate, and VEGF pathways, both acutely and long-term. He gives a four-part weekly exercise framework plus a fifth category: doing something you hate to build the anterior mid-cingulate cortex.
Huberman's claim is that 60 to 70 percent of exercise's effect on brain performance runs through arousal — the catecholamine surge that lifts alertness during and after a session. That makes movement a scheduling lever, not only a fitness one: the window after training is when focus and learning come cheapest. He also covers the slower machinery, bone-released osteocalcin and BDNF feeding hippocampal neurogenesis, plus a weekly shape: one long Zone 2 block of 45 to 75 minutes, one interval session, resistance work and jumps.
