Treadmill Before or After Strength Training? The Right Answer
Hello, this is Kitamura, the owner of Orange Fitness in Kai City, Yamanashi.
“Should I use the treadmill before strength training, or after?” Beginners wonder about this most.
Here is the short answer.
If you want to protect the quality of your lifting (weight and reps), keep the treadmill short before. If your goal is fat burning or fitness, add it after. In other words, don’t fit the treadmill in on willpower. Place it by goal.
The short answer: use this rule if you can’t decide
Before strength training = “preparation”; after = “a bonus”
Before lifting, the treadmill has one job: warm your body up so you can lift better.
After lifting, the treadmill is a “bonus” that adds fat burning, heart and lung fitness, and stamina.
The basic rule (remember just this)
- Priority on muscle size and strength → before: short / after: short to medium if needed
- Priority on weight loss and fitness → before: short / after: medium
- If you’re unsure → 5 minutes before + 10 minutes after (easy) is the least likely to go wrong
By goal: who should add it before, and who should add it after
Who it suits before strength training (you want more power)
If any of these fit, a little time before is worth it.
- Your body is cold and your first set feels heavy
- Your shoulders or hips aren’t so much “stiff” as just “not moving”
- Your form isn’t stable when you go straight into lifting
Before lifting there’s no need to push. “Slightly out of breath” is enough. If you sweat heavily, it eats into your lifting power.
Who it suits after strength training (you want fat burning and fitness)
If any of these are your goal, after is the main slot.
- You want to lose body fat (without cutting your diet hard)
- You get winded on stairs and want more stamina
- You can only come two or three times a week and want to get a lot done in a short time
After lifting, your muscles have been stimulated, so adding light to moderate cardio now also makes it easier to build a habit.
Watch out: the cost of doing too much before
A long session before weakens your lifting
If you’re after muscle size or strength, the quality of your lifting (weight, reps, form) matters most. If you walk for a long time before, your legs tire first and your leg press and similar lifts tend to suffer. The result is a poor trade: “I did the cardio but my lifting was thin.”
Before: “5 to 8 minutes is enough”
On lower-body days especially, it works better not to go long before. Keep it short and steady before. That is the rule.
How we recommend doing it at our gym (30–45 minutes)
The standard if you’re unsure (strength first, minimum cardio)
- Before: treadmill, 5 minutes (slightly out of breath)
- Strength training: 30 minutes from the “big three” of legs, back and chest
- After: treadmill, 10 minutes (an intensity where you can talk)
This is the easiest to keep up and gets good results.
Leaning toward fat burning (while protecting your lifting)
- Before: treadmill, 5 minutes
- Strength training: whole body, 30 minutes (at an intensity you can finish)
- After: treadmill, 15–20 minutes (out of breath but not crushed)
The point is to “add to the after”, not to “add to the before”.
The minimum on busy days (20–30 minutes)
- Before: treadmill, 3–5 minutes
- Strength training: leg press, lat pulldown and chest press, 2 sets each
- (You can skip the treadmill afterward)
On busy days, don’t try to do everything. A plan that doesn’t break wins.
Frequently asked questions
Q. If I’m dieting, should I do long cardio before lifting?
A. We generally don’t recommend it. You tend to get tired first and lift weaker. Even when dieting, lifting is the core, so keep cardio short before and move it after.
Q. Will cardio after lifting make me lose muscle?
A. Not if you don’t overdo it. A guide: stay within a range where you can walk properly and aren’t still tired the next day. What protects muscle is the quality of your lifting plus protein.
Q. Is it OK to have treadmill-only days?
A. Of course. But if you’re after body shaping or toning, just make sure your lifting frequency doesn’t drop. Adding it after a lifting day is the easiest form to keep up.
Summary
The question isn’t “before or after”. Your goal decides where it goes. To protect your lifting, keep it short before; for fat burning or fitness, add it after.
If you’re unsure, this is a good place to start: 5 minutes before + strength training + 10 minutes after (easy). The way you can keep going is the strongest way.
