How do I track my progress at the gym?

Write down every workout: the exercise, the weight, the sets and the reps. That one habit tells you more than anything else, because if your numbers are going up, you're making progress. Everything else is a supporting detail.

What to log

For each exercise:

• Weight used
• Reps for each set
• Optionally, how hard it felt on a 1 to 10 scale

A note on your phone works. So does a spreadsheet, a notebook, or any lifting app. The format doesn't matter. Writing it down before you leave the gym does.

A sample entry:

Bench press: 135 x 8, 135 x 8, 135 x 7

Next time you see that, you know the target is to beat it by a rep.

Other things worth tracking

1. Photos, every 4 weeks, same pose and lighting. Changes happen too slowly to see day to day.
2. Measurements, such as waist, chest or arm, once a month if you like numbers.
3. Bodyweight, if useful. Weigh at the same time a few times a week and look at the weekly average. Day-to-day swings of a few pounds are normal and meaningless.
4. How you feel: energy, sleep, how stairs feel.
5. Streaks and head-to-head results, if you use League of Fitness, which logs workouts synced from Apple Health and keeps your history against each opponent

If tracking your weight makes you anxious or obsessive, skip it. Strength numbers and photos are enough.

For cardio

Track time, distance and an effort measure like average heart rate. A route that takes you 5 minutes less at the same effort a few months later is real progress.

How to read the data

Look at trends over 4 to 8 weeks, not single sessions. Everyone has bad days. If your 5-rep weights on main lifts are rising, you're on track. If you have been flat for six weeks or more, change something, as explained in progressive overload.

Tracking also helps with the mental side. When the mirror is slow, a log that shows you lifting 20 lb more than you were two months ago is hard to argue with. See how long it takes to see results for what to expect.
