How often should you take progress photos?

By David Pintarič, maker of ProgressLens · Updated October 29, 2026

Take them often enough to build the habit, and compare them rarely enough to see a difference.

Short answer

Weekly is the best default: same day and time each week, compared every four weeks. For muscle gain, every one to two weeks compared every 8–12 weeks. Daily photos are fine for challenges like 75 Hard but too noisy to compare day to day.

Why not every day?

Day-to-day changes in water, digestion, light and posture are bigger than real fat or muscle change. Comparing yesterday with today mostly measures noise, and it can be discouraging. Taking photos daily is fine; just don’t judge them daily.

Making it stick

Attach it to something you already do weekly, such as Sunday morning before breakfast. Set a reminder. In ProgressLens you can choose daily, weekly, twice a week or every four weeks, and the reminder tells you which pose to match.

FAQ

Frequently asked questions

Is once a month enough?

Yes if you’re consistent, but a monthly habit is easier to forget. Weekly photos with monthly comparisons give you more data and a stronger habit.

What day should I take progress photos?

Any day, as long as it’s the same one. Avoid the morning after a big meal or a heavy salt day if you can.
