The Lethal Physique Challenge

Applications open for 2026.

After piloting The Lethal Physique protocol, the biggest thing I have found missing in The Lethal Gentlemen’s Club is community.

Working collaboratively on a mission.

Training together.

Grinding together.

Pushing each other to become Modern Renaissance Men.

So I have an opportunity for you all.

How the Challenge will work

Duration: 12 weeks. Long enough for drastic changes to your physique & lethal standards if you lock in. Short enough to stay laser focused.

Deliverables:
i) Lethal Combine: Complete testing process I use with elite athletes & 1-1 business clients.

ii) Training process that has on average improved VO2 max of my clients by 15% & Strength Numbers by ~20% on average.

You will all be onboarded onto training app software.

iii) Performance Nutrition: You will be given everything you need to effectively forge your physique through proper fuelling.

iv) Lethal Mindset & Accountability: each of you in the challenge will be put into a WhatsApp group with direct access to me for miscellanies questions. You will also have an entire curriculum to follow with new themes each & every week of the challenge.

Challenge Prize Winners

The winner of this challenge will be the one who has the most impressive physique & performance transformation.

I want to make this one of the best challenge prize giveaways in the space.

For that reason, the winner will receive:

• Lifetime access to The Lethal Gentlemen’s Club Substack ($300 valuation).

• Exclusive Training gear that has not been released other than to my 1-1 clients ($500 in valuation).

• Custom Winnings Gloves directly from Japan ($1000 valuation).

• Access to Lethal Events that are exclusive only to my current clients (Priceless)

Entry Fee

To join the challenge & have everything you need regarding testing, training, nutrition, mindset & accountability, it will be $500 to participate.

I am in the process of taking applications which will be added to a WhatsApp group where I will be speaking directly with everyone inside to make sure this is the best 12 week challenge that exists in the market.

If you want early access, DM me ‘Lethal Challenge’ & your WhatsApp number to get involved.

I won’t be running this challenge unless we get 50 participants on board.

Stay Lethal.

Jack Krucial.
