Push your endurance capabilities further in whatever discipline you train, with a plan that actually trains and pushes you mathematically. WHY BASE • One adaptive plan across strength + endurance + nutrition. • AI coach that gives feedback, adjusts your plan, and provides insight from your actual numbers. • Live health data synced in, so your plan reacts to how you're really recovering • Precise macro goals that adapt in real time as your training progresses • Built by real hybrid athletes training for both strength and endurance goals
