New Member Bonus: HIIT Builder v3

First, a thank you. This tool exists because of our member Đorđe Sekulić, who took the original HIT Builder and rebuilt it into a far more complete planning and tracking system. He didn’t just build it for himself. He decided to share it with the whole CT community. That’s exactly the kind of contribution that makes this community what it is.

HIIT Builder v3 is now a free bonus for:

• monthly members who have been with us for more than 6 months;
• all Premium members.

And here’s an open invitation to the rest of you. If you have a tool, e-book, or course you’d like to sell through Complementary Training, or simply share with the community, get in touch. We’d like to hear what you’re working on.

Now, what the tool actually does.

Build individualized running-based conditioning without rebuilding the math every time

HIIT Builder v3 is a macro-enabled Excel system for turning athlete testing data into clear running prescriptions for individuals and teams.

Enter the athlete data. Choose the interval method. Adjust intensity, duration, recovery, start loss, change-of-direction loss, and shuttles. The Builder calculates the target velocities and distances, organizes athletes into workable groups, and prepares the session for delivery.

The workbook does the repetitive math. The coach still makes the decision.

What’s new in Version 3

• Program Manager — save, search, load, and reuse complete session templates.
• Running Database — store planned or completed sessions and build a real training history.
• Planned-versus-completed workflow — adjust sets, reps, and RPE when the session differs from the plan.
• Printable velocity profiles — export one athlete or a full squad.
• Curved Run module — plan one-curve and S-run setups.
• Editable drill library — add your own drills instead of being locked into a closed list.

Under the hood: 8 HIIT methods and 74 ready-made drill entries, with MAS-, IFT-, and ASR-based prescription and adjustments for starts and changes of direction.

Who it’s for

S&C coaches, sport scientists, and team-sport practitioners working with running-based conditioning who want a transparent, editable system rather than another black-box calculator.

A quick note on requirements

This is a macro-enabled workbook. Use a current desktop version of Microsoft Excel and enable macros when you open it. It will not run in Google Sheets or Excel Online.
