Why Your Warm-Up Sucks—and How to Fix It

If your second set feels way better than your first working set, your warm-up failed.

That first set should be your best shot. You're freshest. Muscles aren’t tired. Nervous system’s firing clean. That set builds the most tension, gives you the biggest strength and muscle-building benefits, and sets the tone for the whole session.

But if it feels like a half-rep disaster? You didn’t prep right. Let’s walk through what actually works.

1. Start with 5 minutes of light cardio

Nothing fancy. Bike, rower, incline walk, or jump rope. You just want to get warm and raise your heart rate a bit.

Why it matters:

  • Loosens joints and muscles so you move smoother
  • Boosts blood flow so muscles are ready to work
  • Gives your brain and body time to sync up—gets your nervous system alert

Skip this and everything feels slower than it should.

2. Get specific: warm up the actual movement

Let’s say you’re squatting. Your warm-up should look like... squatting.

Start with the empty bar. Focus on clean reps, tight positioning. Then build the weight in small steps. The goal here isn’t to get tired—it’s to fine-tune your technique and teach your body the movement under load.

This is where a lot of people go wrong. They jump straight from the bar to 70% of their work weight and wonder why that first working set feels like garbage. Don’t skip steps.

3. Ramp the load slowly to wake up your CNS

Every set should prep your nervous system for the one after it. You’re not just warming up muscles—you’re warming up intensity.

Here’s an example if you’re working up to a 275 lb squat:

  • Empty bar × 12
  • 135 × 7
  • 185 × 4
  • 225 × 3
  • 275 × 5 (first working set)
    • Bonus: You can take your first working set for a quick ride of 1-2 reps as a primer.

Those lighter sets shouldn’t feel hard. Think of them like mental and physical checkpoints. You’re telling your body, “Here comes more.” And when you finally hit that work weight, you’ll feel ready, not like you’re testing the waters.

Your first working set should never feel like a warm-up

If your second set is cleaner, faster, or stronger... you weren’t ready for the first one.

That first set is your most important one. You’re fresh, tight, and focused. You can create the most tension, which means more strength and better muscle-building. And if you’re tracking progress week to week, you need consistency. That first set is your data point.

So if you change how you warm up every week, you never really know what’s improving.

TL;DR: Do this

  • 5 mins of light cardio to raise your core temp
  • 2-3 light sets using the exact movement you’re about to train
  • Ramp up with small jumps to your working weight
  • Make sure your first set is your best one—not just a throwaway
