Are You Trying Hard Enough in the Gym?

We’ve all been there. You step into the gym, go through your routine, and feel like you’re putting in a solid effort—but are you really pushing hard enough to get the results you want? Strength and muscle growth aren’t just about showing up or moving weight; they’re about the quality and intensity of your effort. Understanding how to gauge that effort can make the difference between plateauing and making serious gains.

At Performax Labs, we believe that knowledge is power. Let’s break down the science-backed ways to measure your effort, and how to optimize your training for maximum growth and strength.

Training to Failure: How Far Is Too Far?

One of the most misunderstood concepts in resistance training is muscular failure. Simply put, failure occurs when you can no longer perform a repetition with proper form. Training to failure has long been touted as a surefire way to maximize muscle growth—but the reality is more nuanced.

Research shows that training to failure can increase muscle fiber recruitment, particularly of the larger type II fibers that have the highest growth potential¹. However, constantly hitting failure can also increase fatigue, impair recovery, and even reduce total weekly training volume. The takeaway? Failure is a tool, not a requirement for every set. Strategic use—especially on your final sets—can enhance hypertrophy without overtaxing your body.

What is RIR?

Reps in Reserve (RIR) is the number of additional repetitions you could perform at the end of a set before reaching failure. For example, if you perform a set of 10 reps and feel you could have done 2 more, that set has an RIR of 2.

Research suggests that training with 1–3 RIR per set is highly effective for hypertrophy². This approach allows you to stimulate muscle growth while preserving energy for additional sets and exercises, helping maintain volume and intensity over the course of a session.

What is RPE?

The Rate of Perceived Exertion (RPE) is a subjective scale that measures how hard a set feels. Typically, RPE is rated from 1 to 10, with 10 representing maximal effort. Using RPE allows lifters to adjust their training intensity based on how they feel on a given day.

• RPE 6–7: Comfortable, leaving multiple reps in reserve

• RPE 8–9: Challenging, with 1–2 RIR

• RPE 10: True maximum effort, reaching failure

By monitoring RPE, you can balance effort and recovery, ensuring you’re pushing hard enough for growth without risking burnout or injury.

Science-Backed Guidelines for Growth and Strength

So how do failure, RPE, and RIR translate into real-world programming? Studies consistently show:

1. Progressive Overload is Key – Gradually increasing weight, reps, or sets over time drives adaptation. Intensity matters, but so does volume.

2. You Don’t Need to Hit Failure Every Set – Training 1–2 reps shy of failure (RIR 1–2) is nearly as effective for hypertrophy while reducing fatigue².

3. Volume Matters More Than Max Effort Alone – Total sets per week per muscle group have a larger impact on growth than training to absolute failure every time³.

4. Strength Gains Require Heavy Loads and Near-Max Effort – For maximal strength, occasional RPE 9–10 sets with compound lifts is beneficial, paired with adequate recovery.

Practical Tips to Gauge Your Effort

• Use RPE as Your Daily Gauge: Start sets at RPE 7–8 and adjust based on how you feel.

• Plan Failure Strategically: Reserve true failure sets for your last set of an exercise or a high-intensity phase.

• Track RIR: Keep a training log noting how many reps you could have done beyond your completed sets. Over time, this helps optimize load selection.

• Listen to Your Body: Fatigue, soreness, and energy levels are valid signals—push harder when you can, back off when you need to.

The Bottom Line

Effort is more than just lifting heavy—it’s about the right combination of intensity, volume, and timing. By understanding concepts like failure, RPE, and RIR, you can fine-tune your training to ensure every session is productive. Maximize your gains without sacrificing recovery, and take the guesswork out of your workouts.
