Begin with fractions
If you can’t do all the sets (or required reps) in a given exercise routine, break it down.
Do 1/5, or 1/4 or 1/3.
Start with 10 reps, not 50.
Do it consistently until you can do more.
Beats exhausting yourself trying to do it all and then inevitably giving up because it’s too difficult.
Small consistent progress almost always outperforms sprints and leaps. It’s also easier.
Applies to fitness, learning, and to most forms of risk.
