The single most powerful performance enhancer on earth is sleep — better than any supplement, better than steroids — and you support it with the right environment, proper electrolytes, and magnesium. I pulled this straight from James DiNicolantonio’s books, and once I applied it, my energy, my athletic performance, and my days on the water all improved. In this Physical Friday I explain why sleep wins and the simple supplements I use to sleep deeper and recover harder.

Sleep. It is the simplest and most powerful thing you can do to improve your performance — on the water, in the gym, and in life — and it beats any supplement or drug. The quality and quantity of your sleep drives your recovery, your energy, and your athletic output. If you want to perform better, the first move is always to sleep more and sleep better, and the rest is built on top of that foundation.
Keep your room very dark, keep your sheets clean and cool, and remove disturbances — especially your phone. Charging your phone in another room keeps you from being pulled out of sleep all night. A dark, cool, quiet, undisturbed environment is the base layer, and it costs you nothing. I set my room up this way every night before I add any supplement on top of it.
Because losing electrolytes through sweat — which fishing guides do constantly in hot environments — can quietly wreck both your daytime performance and your nighttime sleep. As DiNicolantonio explains, sodium restriction raises nighttime adrenaline and impairs sleep. When you replace your water with only plain water all day, you wash out your electrolytes. A high-sodium electrolyte product restores that balance and helps you sleep and perform better.
Magnesium helps you chill out, fall asleep, and stay asleep, and most people are deficient in it. I take a scoop every night before bed, and it is the piece that improves my sleep quality through the night and helps me reach the deep, vivid-dream recovery sleep where the body repairs the most from hard fishing and hard training. Melatonin can help you fall asleep, but magnesium is what helps me stay asleep.
Melatonin helps you get to sleep but, in my experience, does not help you stay asleep. Magnesium is the one that helps me stay asleep and reach deep recovery sleep through the night. I like sleep gummies for melatonin because they deliver it without drinking a lot of liquid before bed, which keeps you from waking up to use the bathroom. I use melatonin to fall asleep and magnesium to stay there.
I make Physical Friday for fishing guides, anglers, hunters, and outdoorsmen who want to stay strong and capable for life. I walk through the full breakdown in the audio above, so press play and listen along.
The biggest takeaway from DiNicolantonio’s book for me was that the greatest performance enhancer on earth is sleep — full stop. It is the simplest lever you can pull, and it outranks anything you can buy. When I started treating sleep as the priority instead of an afterthought, my energy and performance climbed. I explain how that shift changed my training in the episode, so press play in the player above.
Good sleep starts with the room. I keep it very dark, the sheets clean and cool, and my phone charging somewhere else so nothing pulls me out of sleep. I also go to bed and wake up at the same time every day. These are free, simple habits that make the biggest difference. I walk through my exact nightly setup in the episode, so press play in the player above.
Here is the part most active people overlook: sweating all day in the heat washes out your electrolytes, and as DiNicolantonio notes, low sodium raises nighttime adrenaline and wrecks sleep. I keep a high-sodium electrolyte drink going through the hot hours instead of drowning in plain water. I get into how much of a difference that made for my recovery in the episode, so press play in the player above.
I use two more tools at night. Melatonin helps me fall asleep, and a sleep gummy delivers it without a glass of liquid that wakes me up later. Magnesium is the one that helps me stay asleep and drop into deep, vivid-dream recovery sleep where the body repairs the most. I describe exactly how I stack them in the episode, so press play in the player above.

If you want to perform better at anything — on the water, in the gym, in your own life — start with sleep. It is the cheapest, most powerful upgrade there is.
Build the dark, cool environment, lock in a consistent schedule, replace your electrolytes, and add magnesium at night. Listen to the full breakdown and the book I leaned on by pressing play in the player above.
