How to Use Resistance Mode

If you've been wondering about resistance mode in TrainerDay, you're not alone. Based on what users have told me, there's some confusion about when to use it and how it differs from ERG and slope modes.

What Resistance Mode Actually Does

Resistance mode sets your smart trainer to a specific percentage of its maximum resistance - think of it as a fixed load that doesn't change automatically. Unlike ERG mode, which adjusts resistance to hit specific power targets, resistance mode maintains a steady resistance level regardless of your speed or cadence.

One user described it perfectly: "It lets me do a complete interval at a predetermined resistance level and see how I do in terms of power. If I pedal faster, I produce more power. Pedal slower and I produce less power."

When Resistance Mode Makes Sense

Resistance mode is mostly when for when your trainer does not support slope mode, but either can be use for

• Sprint training where you need quick resistance changes
• Strength work that focuses on pushing against a consistent load
• Track-style workouts with standing starts
• Training that mimics fixed-gear riding
• When you want to replicate the feel of a traditional "dumb" trainer

I've seen users successfully use resistance mode for ReHIT (Reduced-Exertion High-Intensity Training) workouts, where ERG mode's power-matching behavior can be too slow for the rapid transitions needed.

The Key Difference from Other Modes

Here's what sets resistance mode apart:

• ERG Mode: Automatically adjusts resistance to maintain target power
• Slope Mode: Simulates road grade, changing resistance based on speed and virtual terrain
• Resistance Mode: Maintains a fixed resistance percentage until manually changed

The key is that in resistance mode, you're in complete control of the resistance level. The trainer won't make any automatic adjustments - it just holds steady at whatever percentage you set.
