One of the biggest mistakes I see is people treating training like a template. They find a program online, copy it exactly, and assume it will work the same way for them. But the truth is simple: the program is never the boss — your body is.
Science matters. Biomechanics matter. New methods can be useful. But none of that means anything if your body isn’t responding the way it should. Two people can do the same exercise with the same form and still feel it in completely different places — because structure, mobility, weak points, and nervous system efficiency aren’t the same for everyone.
That’s why feedback is everything. When you train, pay attention to what’s actually happening: where you feel the tension, which side takes over, where you lose control, what gets sore the next day, and what never seems to improve. Those signals tell you more than any trend or influencer routine.
So the goal isn’t to blindly follow someone else’s plan. The goal is to become the kind of athlete who can listen — and adjust. If an exercise doesn’t hit the target muscle, change the setup. If the technique is correct but the feedback is wrong, change the angle. If your recovery isn’t keeping up, change the schedule. The strongest program is the one that matches your body.
Train smart. Use the plan — but let your body write the final version.
