FAQ
Questions about the books
How do the books work?
Every book is an instant digital download through Gumroad. You pay securely there and get a download link by email. Your files stay in your Gumroad Library.
Can I read them on my phone or Kindle?
Yes. Every book is a PDF that works on any phone, tablet or computer. Increase Stamina in Bed also comes as an EPUB for Kindle (via Send to Kindle) and Apple Books.
Are the books explicit?
No. They’re written in clear, respectful language.
Who writes them?
I do. I’m Sam Smith, a men’s fitness and stamina coach with more than 10 years of experience. I’m a coach, not a medical doctor, and my books are educational.
What’s the difference between the books and the plans?
The books are self-guided. The personal nutrition plan ($79) is written for you from a questionnaire, and the coaching option ($149) adds 4 weekly check-ins with me.
Educational content, not medical advice. Sam Smith is a fitness coach, not a medical doctor. Check with your doctor before starting a new exercise or nutrition plan, or if you have any health concern. Results vary; no specific outcome is promised.
