Do I need the Performance System to use the other programs?
No. Each program stands alone. But if you want the complete progression, start with the Performance System — it includes all four phases.
Can I run Sprinting alongside another program?
Yes. Sprinting pairs well with any strength program. Three sessions per week, designed to complement your lifting days.
Is Fuel a meal plan?
No. It's a fueling system — macro framework, timing protocols, and supplement stacks. Not a restrictive diet. A system for people who train hard and eat like it matters.
What format are the programs?
PDF and spreadsheet. Open on your phone or print it out. No app required. No subscription. One payment, you own it forever.
Is there a guarantee?
Yes. Follow any SISU program for 4 weeks. If you don't feel a measurable difference, you get a free 30-minute consult with our team. We'll figure out what's not working and make it right.
Pick your system.
Structured programs. One payment. You own it forever.
