For the past few off-seasons, Padres pitcher Joe Musgrove has been working out with Deep End Fitness, an intense, yet calm workout regimen that includes on land and underwater breathing drills and workouts. Participants do breath work poolside before outlining accountability goals and individual intentions, before hopping into a thirteen foot-deep pool. The underwater drills include calm, breath holding, to walking the length of the pool carrying 40-pound weights. Other times their are group drills.
Deep End Fitness was founded by a pair of former Marine Raiders. Musgrove has not been alone in his training. He has brought along fellow pitchers and even Fernando Tatis Jr. On a recent outing, a group of Padres pitchers and catchers joined in at a La Jolla pool as a small group of locals looked on.
