Module 2: Progressive Overload & Pacing

Progressive Overload & Pacing

Sports Science · 10 min read · Week 2

To get stronger without breaking your body, you must use progressive overload. This means gradually increasing the stress you put on your body so it has time to adapt. You can do this by adding more weight, doing more reps, or even just working out more often. However, there is a "sweet spot." Your body goes through three stages when stressed: the alarm (initial soreness), resistance (building strength), and exhaustion (overtraining).

The goal is to stay in the "resistance" phase. A good rule of thumb is the 10% Rule: don't increase your total weekly work (time, weight, or distance) by more than 10% each week. If you can easily do two extra reps on your last set for two weeks in a row (the 2-for-2 rule), you are likely ready to increase the challenge. If you ignore these signs and push into exhaustion, you risk common injuries like stress on the lower back or knees.

Why it matters for 75 Hard

Avoiding the "Honeymoon" Crash: It's tempting to go 100% in Week 1, but "packing on the poundage blindly" leads to burnout and injury.
Smart Pacing: Since you are doing two workouts a day, use one for high-intensity and the other for lower-intensity (like Zone 2 cardio) to keep your body from reaching the "exhaustion" stage.
Long-term Wins: Progressive overload ensures you are still making gains on Day 75, rather than just surviving.
