Your 1-rep max and why it should drive your programming

Your 1-rep max and why it should drive your programming — practical advice from Saddie, your AI fitness coach.


Your 1-rep max (1RM) is a powerful tool in your fitness journey. It’s not just a number to impress your friends at the gym; it’s a benchmark that can help you tailor your training program to your specific goals. Understanding and utilizing your 1RM can enhance your strength gains, improve your lifting form, and ultimately lead you to better results. Let’s dive into how you can use this crucial number to drive your programming effectively.

Understanding Your 1-Rep Max

Your 1RM is the maximum amount of weight you can lift for one complete repetition of a given exercise, such as the bench press, squat, or deadlift. It’s essential to know this number because it represents your current strength level. But how do you find it safely?

While you can attempt to lift heavy weights to determine your 1RM directly, I recommend a more cautious approach, especially if you're new to lifting. Instead, you can calculate your 1RM using submaximal lifting. For example, if you can lift 80% of your maximum for five repetitions, there are formulas (like the Epley or Brzycki) that can help you estimate your 1RM based on those figures.

Once you've established your 1RM, keep it handy — it will guide your training intensity and volume.

Programming with Your 1RM in Mind

Now that you know your 1RM, how do you use it to inform your training? Here are a few practical ways to incorporate it into your programming:

1. Set Your Training Intensities: Your 1RM will enable you to determine the percentage of weight to lift for various goals. For hypertrophy (muscle growth), you typically want to work at 65-75% of your 1RM for 6-12 reps. For strength, aim for 80-90% for lower reps (1-5). Using these percentages can help you structure your workouts effectively.

2. Progressive Overload: Knowing your 1RM sets a baseline for progressive overload, which is key to making gains. Each week, aim to increase your lift by a small percentage or a small amount of weight. This gradual increase will challenge your muscles and lead to growth over time.

3. Tracking Progress: Regularly reassessing your 1RM allows you to track your progress accurately. A good rule of thumb is to retest every 6-8 weeks. This keeps you motivated and ensures that you’re continually pushing your limits.

4. Tailoring Accessory Work: Your 1RM also provides insight into your strengths and weaknesses. If you find that your 1RM is significantly lower for a particular lift compared to others, consider incorporating accessory exercises that target the muscles involved in that lift. For instance, if your deadlift is lagging, you might benefit from additional hamstring and lower back work.

Avoiding Common Pitfalls

While working with your 1RM is beneficial, there are some pitfalls to avoid:

Using your 1-rep max as a guide can help you create a well-structured and effective training program. Tools like Saddie, your AI fitness coach, can assist you in personalizing your workouts based on your 1RM, ensuring you stay on track and motivated.
