What You Get In Today’s Gainzmas Deal
Perfect for lifters and CrossFitters who want high‑touch transformation coaching and also want their crew getting better right alongside them, without money being the excuse.
What’s included:
- Your coaching spot – Join 3 months of Foundations or 1 month (minimum) of Comprehensive coaching (each $500) and get full access to expert guidance on training, nutrition, and lifestyle.
- Five $100 friend codes – You’ll receive 5 separate codes worth $100 each so up to five friends can join you on a qualifying program or coaching option.
- Simple claim process – After purchase, email help@thundrbro.com with your order info and “Gainzmas Friend Codes” in the subject line, and the team will send you your 5 unique codes to share.
This exact “buy your spot, bring 5 friends” deal only exists for today’s Gainzmas offer. At midnight EST, it expires and a new deal replaces it.
