Vitamin D by Derek T Larson
Sweaty, Smiling & Centered
Free · In‑App Purchases
Most apps give you workouts.
This one gives you a life.
Vitamin D is built around three things every man and woman needs to thrive — Body, Mind, and Soul. Not as concepts. As a daily practice. As a way of being.
BODY
Ten minutes. Every morning. No gym. No equipment. No excuses. High definition outdoor workouts filmed on the beaches and bluffs of Laguna Beach, California — scored with original soul music composed exclusively for this app. You’ll be sweating before you know it and smiling before you’re done.
MIND
Real insights from real study. Think and Grow Rich. 75 Hard. Morning sunlight. Cold water. The daily disciplines that separate the people who talk about changing their life from the people who actually do it. Derek shares what he’s learning as he learns it — raw, honest, and earned.
SOUL
This is where it gets personal. Behind the scenes of a life being rebuilt from the ground up. The music. The journey. The man. Derek T. Larson — the King of Sing — is recording 100 songs and reclaiming the voice he’s carried his whole life. You get a front row seat.
This isn’t a fitness app.
It’s a front row seat to what happens when a man finally decides to become who he always was.
