Jen Blackstock Performance Coaching in Carlsbad's Aviara corridor holds NASM personal-training, RRCA run-coaching, and CranioSacral Therapy certifications under one practice. That combination of strength programming and endurance periodization mirrors the integrated approach at Breathe Degrees, where heated-room mobility work complements outdoor training loads. Coaching since 2013, the practice builds custom 1:1 programs spanning life strategy, business performance, and run training from 5K through full marathon distance. Women-owned and operating from Embarcadero Lane near Batiquitos Lagoon, the studio layers nutrition coaching atop structured training blocks, a recovery-forward model shared with Red Lotus Wellness Center on the integrative-health side. Race-prep cycles apply RRCA-standard progressive mileage builds with VO2max interval sessions calibrated to individual lactate-threshold benchmarks.
