A little preview of how I warm up for class.

Skipping the warm up is the fastest way to leave gains on the table. A proper warm up increases blood flow to working muscles, reduces injury, raises core temperature, and activates the neuromuscular connections your body needs to recruit muscle fibers efficiently. I always see people enter the gym and go straight the weights. Stop that!! 😅

Tennis blends physical and cognitive challenges in a way most gym training doesn’t. Learning a new motor skill in my 30s has been a deliberate cognitive stimulus, one I didn’t fully appreciate until I started showing up to lessons and feeling genuinely humbled. 🎾

The Copenhagen City Heart Study found that tennis may add up to 9.7 years to life expectancy, more than any other sport studied including running, swimming, and cycling.

It challenges both the anaerobic and aerobic system with sustained activity, contributing to heart and brain health. Sustained energy = real sweat output.
Grip strength is also a byproduct, and research increasingly identifies it as a biomarker of aging.

I was at a trade show, told a supplier what i was building, and they laughed. in my face.

and the only thing i felt was clarity. if the people who make the materials don’t think it’s possible, that’s not a reason to stop. that’s the whole reason to keep going.

study one: University of New Mexico, Toxicological Sciences, February 2024. 62 human tested. microplastics found in all 62. concentrations ranging from 6.5 to 790 micrograms per gram of tissue. , the plastic in your water bottles, made up 54% of what was found. PVC, a known , was another 10%.

study two: same institution, same journal, May 2024. 23 human samples tested. microplastics in every single one. average concentration 329 micrograms per gram of tissue. a higher concentration in the samples correlated with lower s***m count. The men in this study averaged 35 years old, meaning their exposure started before plastics were even this widespread so the researchers flagged that the impact on younger generations is likely even more severe.

there is currently no established safe level of microplastics in human tissue. what that means is we are accumulating something we have no threshold for. that’s what unsettled me most.
part two is the protocol to get them out. follow and save so you don’t miss it.

I used to wash down a handful of my supplements together all at once.. Now, I audit every supplement in my stack and build a schedule around my meals. that’s the difference between having a protocol and an expensive habit.

These are common mistakes that people make when taking supplements.

save this. part 2 drops with my exact stack and when i take them.
