The image features a tweet from Bret Contreras, PhD, discussing weightlifting and training intensity. The mood is informative and motivational, aimed at encouraging readers to push their limits in the gym.
Text in image: The average lifter chooses to lift around 50% of their 1RM for around 10 reps, according to a recent meta-analysis. So if someone could lift 200 lbs for one rep, they’d select 100 lbs for a set of 10 reps.

With this load, they’re leaving around 10 reps in the tank – meaning they could do 10 more reps if they went all out (to failure).

This is the main reason why people don’t tend to see much results in the weight room. They just don’t train very hard.

If you want to build an appreciable amount of muscle, you have to train a lot harder than you think and push it a lot harder than the average lifter.
