Progressive Overload Explained

Training comic · April 10, 2026 · 6 slides

Progressive overload is the foundation of muscle growth and can be achieved through several different training adjustments. Lifters can add more weight, perform more repetitions, increase the number of sets, or slow down their lifting tempo to increase time under tension. Consistently tracking these variables is essential to ensure continuous progress over time.

The GainFrame mascot adds a small weight plate to a barbell, illustrating how adding even a small amount of weight contributes to progressive overload.
1. Add More Weight. The most obvious method. Even 2.5lbs per side counts. +5 lbs. 100 lbs. 105 lbs.
The GainFrame mascot sweats while curling dumbbells, demonstrating that increasing the number of repetitions with the same weight is a form of progressive overload.
2. Add More Reps. Same weight. More reps. Still progressive overload. 8 reps. 10 reps.
The GainFrame mascot points to a checklist on an easel showing four completed sets, explaining that adding more sets increases total training volume.
3. Add More Sets. More total volume = more growth stimulus. Set 1. Set 2. Set 3. Set 4. +1 Set.
The GainFrame mascot performs a slow squat next to a stopwatch, showing how slowing down the tempo increases time under tension for muscle growth.
4. Slow Down The Tempo. More time under tension = more muscle breakdown = more growth. Time Under Tension. 3 sec down... - 1 sec pause... - 2 sec up.
