If you only understand one thing about strength training, make it this: your body adapts to the stress you give it, so the stress has to progress over time. That's progressive overload, and it's the engine behind every program that works.
What it actually means
Progressive overload means gradually asking more of your body. Most people think that only means adding weight, but there are several ways to do it.
Add weight to the bar
Add reps at the same weight
Add a set
Improve your technique or range of motion
Reduce rest or slow your tempo
You don't need to progress every session, just over weeks.
Why most people stall
The most common reason isn't a lack of effort. It's that nothing is written down. If you can't see what you lifted last week, you can't try to beat it, and the gym becomes a place to get tired rather than get stronger.
A simple way to apply it
Pick a rep range, such as 6 to 8 reps. When you hit the top of the range on every set with good form, add a little weight next session. If you can't, stay at the same weight and try to add a rep. That's it.
Track it where you'll actually use it
A logbook works, but a program that tells you what to lift and records it makes it much easier. That's why every program purchase from JASHTONFIT comes with your first month free on the JASHTONFIT app. If you want a structured plan built around you, take a look at the 8-Week Personalised Plan here.
