Marcus Webb

Former D1 Swimmer · Strength Coach · Cold Therapy Specialist

I swam competitively at the D1 level for four years. After finishing my athletic career, I became a strength and conditioning coach — and spent the next decade trying to optimize recovery for high-performance athletes.

In 2019, I started systematically integrating cold water immersion into client protocols. Not because it was trending — because the research was compelling and I wanted to track the outcomes myself.

What I Track

• Core body temperature response curves
• HRV recovery metrics pre/post immersion
• Norepinephrine and cortisol panels (quarterly)
• Client-reported sleep quality and soreness scores
• Long-term adaptation timelines (6-month benchmarks)

Why Ice Basin

I built this site because most cold plunge content online is either company marketing or bro-science. There is a middle ground — evidence-based protocols that actually work for real people with real schedules. That is what I write about.

No sponsored posts that I do not disclose. No protocols I have not tested. No science I cannot cite.
