• A strategy I use to overcome workout plateaus and re-ignite muscle gains is to manipulate frequency vs volume. Recently my leg workouts started to stall, so I separated "leg day" into 2 different days. Now I'm doing hamstrings and calves on one day, and quads on another. With this new split the frequency in which I train these muscles decreased (once every 6 days), while the volume per workout increased. And after only 2 weeks, I can tell leg gains have come back to life.
• Here's what the rest of my split looks like:
  • Day 1: Shoulder / Chest (some triceps)
  • Day 2: Back (some biceps)
  • Day 3: Quads (and abs)
  • Day 4: Biceps and Triceps
  • Day 5: Hamstrings and calves
  • Repeat
• As you can see, I mix and match this volume-frequency idea. For example, my arm training is much higher frequency, but lower volume per workout.

• I've been talking about Aquaman, my water filter, a lot lately. People are surprised that a dentist would want to filter out fluoride. But if you don't eat sugar or many carbohydrates and have good oral hygiene, I think the risks of fluoride consumption outweighs any benefits. Here's a study I hadn't seen until "Crypto Diggy" shared it with me on twitter - fluoride consumption during pregnancy linked with children having lower IQs.    

• YC, the world's most successful startup incubator, had "Demo Day" this week, which gives us a peek at up-and-coming businesses / ideas that can shape our future. The big trend this year seems to be biotech. Companies are making immunotherapies, cell transplants for chronic diseases, and telomere editing to reverse aging. Reading about these companies, I can't help but think none of them would exist if we focused on eating right, working out, sleeping and getting some sunlight.
