I had someone show me their workout last week.
Single-leg squats on a bosu ball while doing bicep curls. Some kind of plank variation that involved moving their arms and legs at the same time. Burpees with a medicine ball overhead.
When I asked what muscle groups they were trying to work, they just stared at me.
“I don’t know. It looked hard.”
Yeah. It looked hard. Also looked like a great way to accomplish absolutely nothing except feeling tired and confused.
Here’s what nobody wants to hear: the exercise that makes you feel like you’re dying isn’t necessarily making you better. And the exercise that looks impressive on Instagram might be completely useless for your goals.
The Only Principle That Actually Matters
Progressive overload.
That’s it. That’s the entire game.
If you want to get stronger, build muscle, increase endurance, or improve mobility, you need to gradually increase the demand on your body over time. More weight. More reps. More range of motion. More control. Something has to progress.
Research on strength training adaptations shows this consistently. A 2017 meta-analysis in Sports Medicine found that progressive overload is the primary driver of hypertrophy and strength gains across all training populations. Doesn’t matter if you’re 25 or 65, beginner or advanced. Same principle applies.
But here’s the problem: you can’t progressively overload an exercise you can barely complete.
If you’re struggling just to do the movement, where’s the room to add weight? To add reps? To make it harder next week?
There isn’t any.
The Push Up Problem
I’ve had at least a dozen clients come to me frustrated because they can’t do push ups.
They’ve been trying for months. Every workout, same routine. Get down on the floor, struggle through a few reps that look like they’re trying to hump the ground, feel like failures.
One woman, 42 years old, told me she’d been doing “push ups” for six months. Zero improvement. When I watched her do one, her hips sagged, her elbows flared out like she was trying to fly, and she barely moved three inches.
That’s not a push up. That’s just suffering on the floor.
Not her fault. Nobody taught her there was another way.
I was the same with pull-ups. Spent years thinking I just “wasn’t strong enough” because I couldn’t do one. Felt like a failure every time I tried.
Then someone showed me I could use bands. Work on negatives. Do rows to build the same muscles. Actually scale the movement.
Six months later, I could do pull-ups. Not because I magically got stronger. Because I stopped trying to force a movement I wasn’t ready for and started doing versions I could actually progress.
The Neural Adaptation Trap
Here’s something that messes people up.
When you first start an exercise, most of your early “gains” are neural. Your brain is just learning the pattern. Figuring out which muscles to fire, when to fire them, how to coordinate the movement.
Research on motor learning shows this initial phase can last 3-6 weeks depending on the complexity of the movement.
You’re not actually getting stronger yet. You’re getting better at the specific skill.
Which is fine… if you stick with it long enough to get past that phase.
But most people don’t.
They do an exercise for two weeks. Don’t see results. Switch to something else. Do that for two weeks. Switch again.
They’re constantly in the neural adaptation phase. Never actually building strength or muscle.
I see this with people who follow those “30-day challenges” or workout programs that change every session. Feels like you’re doing a lot. Feels like variety is good.
But you’re just getting really good at being a beginner.
The Pattern Looks Like This:
Week 1-2: Learning the movement, brain figuring it out, reps getting slightly easier
Week 3: Starting to feel good, progress happening, could probably add weight soon
Week 4: “I should switch things up for variety”
Back to Week 1 with a completely new movement
Never actually get strong
A 2019 study in the Journal of Strength and Conditioning Research found that exercise variation frequency matters. Too much variation and you don’t adapt. You need enough consistency to actually improve, then strategic variation when progress stalls.
Not before.
What Makes An Exercise Actually Good
Forget what looks cool. Forget what feels hardest.
A good exercise is one you can scale up or down based on where you actually are.
Can you make it easier so you can start? Can you make it harder once it becomes manageable?
If the answer is no, it’s probably not a good exercise for you right now.
Example: The Pull Up
I had a 38 year old guy who’d been trying to do pull ups for eight months. Still couldn’t do one. Just kept trying the same thing over and over.
His approach: Jump up, hang there, struggle, drop down. Repeat until exhausted. Make zero progress.
What we did instead:
Week 1-2: Cable pull downs. Built pulling strength in a movement he could actually do. Started with 3 sets of 8, worked up to 3 sets of 12.
Week 3-4: Band-assisted pull-ups with a thick band. Practiced the actual pattern with help. Went from barely moving to solid reps.
Week 5-6: Reduced band thickness. Made it harder as he got stronger.
Week 7-8: Negative pull ups. Jump up, lower down for 5 seconds. Built eccentric strength.
Week 9-10: Partial range pull ups from the top position. Then from the bottom. Then full range.
Week 11: First unassisted pull up.
Each step could be progressed. Add reps. Add weight. Slow down the tempo. Remove band assistance. There was always a next level.

Example: The Squat
Had a 55 year old client with knee pain who thought she couldn’t squat anymore. Every time she tried, sharp pain. Stopped training legs entirely for three months.
We didn’t start with barbell back squats. Started with box squats to a high box. 18 inches. Controlled the depth so she knew exactly where to stop. No pain. Built confidence. Strengthened the pattern.
Two weeks later, lowered the box to 16 inches. Two weeks after that, 14 inches. Added a goblet hold with a light dumbbell. Then a heavier one. Eventually worked up to barbell front squats.
Three months total. Now she squats pain free with 95 pounds for reps. More weight than before her knee issues started.
Could’ve just said “squats hurt, don’t squat.” Instead we found a version that worked and built from there.
The Testing Problem
Here’s another thing people miss: you need to test outside the exercise.
If you only measure progress by the exercise itself, you don’t know if you’re actually getting stronger or just getting better at that specific movement.
I have a client who trains goblet squats three days a week. Gets better at goblet squats. Adds weight. Feels good.
But every 4-6 weeks, we test her barbell squat. That tells us if she’s building actual leg strength or just getting good at holding a dumbbell.
Same with push ups. Train push ups, test with a dumbbell chest press. Are the numbers going up on both? Then you’re building real strength. If only one is improving, you’re probably just getting skilled at one movement.
For endurance, we use standardized tests that don’t change. For mobility, specific assessments we track over time.
This is why people get frustrated. They do the same movements over and over, see small improvements in that exact movement, but don’t actually feel stronger or better in real life.
Because they never built transferable strength. They just got good at one thing.
So What Do You Actually Do?
Step 1: Pick exercises you can actually do well
Not exercises that wreck you. Exercises where you can maintain good form, complete the reps, and feel the right muscles working.
If you can’t do that, scale down.
There’s no shame in starting easier. There’s only shame in doing something poorly for months and never improving.
Step 2: Stick with them long enough to progress
At least 6-8 weeks before you switch. Give your body time to actually adapt, not just learn the movement.
Add reps. Add weight. Add tempo. Decrease rest. Something needs to increase over time.
Track it. Write it down. If the numbers aren’t going up, something needs to change.
Step 3: Test outside the movement
Every 4-6 weeks, test something different that measures the same quality.
Are you actually getting stronger? Building muscle? Moving better?
If not, the exercise isn’t working. Either scale it differently or pick something else.
Step 4: When progress stalls, scale up or change the stimulus
Once you’ve milked an exercise for everything it’s worth, then you change it. Not before.
If you’ve been doing the same weight for the same reps for three weeks straight with no improvement, time to adjust. Make it harder. Add a variation. Change the angle.
But only after you’ve given it a real shot.
The Bottom Line
The best exercise isn’t the hardest one.
It’s not the one that looks coolest on social media.
It’s not the one everyone else is doing.
It’s the one you can do well right now and progress over time.
My client who couldn’t do a push up? Went from zero to ten in six weeks. Not because push ups are magic. Because we found a version she could actually scale and built from there.
The guy doing single leg bosu ball exercises? Still doing them. Still not seeing results. Still wondering why his numbers haven’t changed in four months.
Pick exercises you can scale. Progress them consistently. Test if they’re actually working.
That’s it. That’s the whole game.
