What Does "Lift at 75%" Actually Mean — And How Do You Figure That Out?

A beginner's guide to training percentages, finding your numbers, and using them to get stronger without burning out.

You've seen it in a workout. "Back squat at 70% for 5 sets of 3." Or "Deadlift — build to 80% of your 1RM."

And if you're newer to lifting, your first thought might be: 70% of what, exactly?

That's a fair question — and an important one. Because training with percentages is one of the most effective tools for building strength consistently and safely. Once you understand it, it changes the way you approach every lift.

Let's break it down from the beginning.

What Is a 1RM — and Why Does It Matter?

1RM stands for one-rep max. It's the maximum amount of weight you can lift for a single repetition with good form. Every percentage in lifting is based on this number.

If your back squat 1RM is 200 lbs, then:

PercentageWeight (based on 200 lb 1RM)What It Feels Like50%100 lbsWarm-up, technique work — should feel easy60%120 lbsLight — controlled, smooth reps70%140 lbsModerate — some effort, still comfortable75%150 lbsWorking weight — challenging but sustainable80%160 lbsHeavy — focused effort, limited reps85%170 lbsVery heavy — form must be sharp90%+180 lbs+Near-maximal — reserved for peak training days

Training at different percentages on different days is called periodization — and it's the foundation of how serious strength programs are built. Light days let you recover. Heavy days build peak strength. Working in the middle builds your baseline.

But What If You're a Beginner and Don't Have a 1RM?

Here's the good news: you don't need to test a true 1RM to start training with percentages. In fact, for most beginners, we recommend against maxing out right away. Your nervous system and technique aren't yet dialed in enough to make that number reliable — or safe.

Instead, use one of these three beginner-friendly methods:

Method 1: Use a Rep Max and Estimate

Pick a weight you can lift for 3–5 solid reps. Use this simple formula to estimate your 1RM:

Estimated 1RM = Weight Lifted × (1 + Reps ÷ 30)

Example: You deadlift 135 lbs for 5 clean reps.
135 × (1 + 5 ÷ 30) = 135 × 1.167 = ~157 lbs estimated 1RM

Now you have a working number to calculate percentages from. It won't be perfect — but it gives you a starting point that keeps training safe and progressive.

Method 2: Use RPE (Rate of Perceived Exertion)

RPE is a 1–10 scale of how hard a set felt:

• RPE 6–7: Could do 3–4 more reps. Feels comfortable.
• RPE 8: Could do 2 more reps. Working hard but in control.
• RPE 9: Could do 1 more rep. Heavy. Focused.
• RPE 10: Could not do another rep. Maximum effort.

When a coach says "lift at 75%," they often also mean something in the RPE 7–8 range. If you don't know your 1RM yet, chasing that feeling is a valid way to find your working weight — and over time, you'll learn exactly what those numbers mean for your body.

Method 3: Start Light and Build Over Weeks

The simplest approach for true beginners: start with a weight that feels like a 6 or 7 out of 10. Track it. Add a small amount each week. After 4–6 weeks of consistent training, you'll have a much more reliable baseline to work from — and you'll have built the technique foundation to test a true max safely.

The goal in your first few months of lifting is not to find your max. It's to build the habit, the movement patterns, and the foundation that makes your future max worth chasing.

How to Find Your Percentages for the Major Lifts

Each lift has its own personality. Here's what to know about establishing your baseline for the big ones:

🏋️ Back Squat

The back squat is the king of lower body strength. Your squat numbers tend to be among the highest of your major lifts because it uses the largest muscle groups — quads, glutes, hamstrings, and core all working together.

How to find your starting weight: Warm up with an empty bar. Add weight in small increments — 10 lbs at a time for women, 20 lbs for men — until you reach a weight that feels like an RPE 7–8 for 3 reps. That's your starting working weight. Multiply by ~1.1 to estimate a 1RM.

Example: 3 solid reps at 135 lbs (RPE 8)Estimated 1RM ≈ 135 × 1.1 = ~148 lbs70% training weight ≈ 104 lbs → round to 105 lbs

🏋️ Deadlift

Most people can pull more than they can squat — the deadlift is typically the highest 1RM of any major lift. It's a hip-hinge movement that prioritizes the posterior chain: glutes, hamstrings, and lower back.

How to find your starting weight: Same progressive warm-up approach. Because the deadlift starts from a dead stop (no bounce), it's easier to honestly assess effort. Find 3 strong reps at an RPE 8 and estimate from there.

Example: 3 reps at 175 lbs (RPE 8)Estimated 1RM ≈ 175 × 1.1 = ~192 lbs75% training weight ≈ 144 lbs → round to 145 lbs

🏋️ Front Squat

The front squat is technically more demanding than the back squat and almost everyone lifts less weight in it — typically 80–85% of their back squat. It's a great tool for building quad strength and improving overhead positioning.

Quick estimate: Multiply your back squat 1RM by 0.82 to get a rough front squat starting point.

Back squat 1RM: 200 lbsEstimated front squat 1RM: 200 × 0.82 = ~164 lbs70% training weight ≈ 115 lbs

🏋️ Overhead Press (Strict Press)

The strict press is typically the lowest 1RM of the major barbell lifts — and that's normal. Pressing weight directly overhead with no leg drive is genuinely hard. Most people press roughly 60–65% of what they bench.

How to find your starting weight: Start with just the bar and focus on form first. Add weight slowly. Because the press has a smaller margin for error (position matters enormously), technique development comes before heavy loading.

Example: 3 solid reps at 75 lbs (RPE 8)Estimated 1RM ≈ 75 × 1.1 = ~82 lbs70% training weight ≈ 57 lbs → round to 55 lbs

🏋️ Power Clean / Hang Clean

The Olympic lifts are different from strength lifts — they're speed-dependent, which means you almost never train them at high percentages. Even elite Olympic lifters spend most of their time at 70–80% of their 1RM. For beginners, technique is everything and weight is secondary.

How to find your starting weight: Work with a coach to establish technique first. Once movement is clean and consistent, a 3-rep RPE 7 gives you a safe baseline to calculate from. Don't rush this one.

Example: 3 technically sound reps at 95 lbs (RPE 7)Estimated 1RM ≈ 95 × 1.1 = ~105 lbsMost training sessions: 70–80% → 73–84 lbs

A Simple Rule for Beginners: The 10-Pound Rule

Before you get too deep into percentages, here's the most important truth for new lifters:

When you're a beginner, you're going to get stronger every single week just by showing up consistently. Don't overthink the math. Add 5–10 lbs to your lifts each week, keep your technique sharp, and the numbers will follow.

Percentage-based training becomes most valuable once your progress starts to slow down — typically after 3–6 months of consistent training. At that point, structured programming with specific percentages helps you continue making progress when simple "add weight every week" stops working.

Until then? Show up. Lift with intention. Track your weights. And trust the process.
