Measurements — your quiet, consistent progress engine

Progress doesn’t always show up as a new PR. Sometimes it’s a steadier waistline, a healthier trend in body weight, or the confidence that comes from seeing the same effort add up over time.

OpenLift’s Measurements feature is built to support that kind of progress: calm, consistent, and motivating. You can log key body metrics, attach notes and context, add progress photos, set goals, and view trends that help you stay grounded in what’s actually happening.

What you can track (in one place)

A single measurement check-in can include one or many of these:

Core

• Weight (entered in your preferred unit; stored consistently behind the scenes)

Body composition (manual or auto-estimated when enough info is available)

• Body fat percentage
• Muscle mass
• Lean body mass
• BMR (Basal Metabolic Rate)
• BMI (both entered and calculated)
• Water percentage
• Visceral fat level
• Metabolic age

Circumference measurements

• Chest, shoulders
• Biceps (left/right), forearms (left/right)
• Neck, waist, hips
• Thighs (left/right), calves (left/right)

Logging a measurement (fast, flexible, and forgiving)

When you log a measurement, OpenLift supports:

• Custom measurement date/time so you can record when it actually happened.
• Context fields like location, equipment, and notes so your data stays meaningful (example: “morning, fasted” vs “after training”).
• Multiple metrics in one check-in (weight + tape measurements + composition, if you want).

Helpful guardrails (to reduce typos)

OpenLift validates common ranges (for example, weight and typical circumference ranges) to help catch “oops” entries before they pollute your charts.

Auto-calculations (optional, but really useful)

When you provide enough information, OpenLift can automatically calculate helpful estimates so you don’t have to do extra work:

• BMI when weight + height are available
• Body fat percentage when circumference measurements + profile info are available
• Lean body mass derived from weight + body fat %
• Muscle mass as an additional estimate
• BMR when weight + age + height + gender are available

OpenLift includes multiple common calculation methods internally (for example, Navy/YMCA/CUN-BAE for body fat; Boer/James/Hume for lean body mass; Mifflin-St Jeor/Harris-Benedict for BMR). As we expand the feature, you’ll see more opportunities to personalize these based on your preferences.

Note: these calculations are best used as consistent estimates—great for trends, not medical diagnosis.

Edit or delete check-ins anytime

Life happens, and logging isn’t always perfect.

• Update a measurement entry to fix values, adjust notes, or add more details later.
• Delete a measurement entry when you don’t want it in your history anymore.

When a measurement entry is deleted, OpenLift also attempts to clean up any attached progress photos to keep your storage tidy.

Your history, your way

Measurements aren’t useful if you can’t review them. OpenLift lets you:

• Browse your measurement history with paging (so it stays fast).
• Filter by date range.
• Filter by measurement type (e.g., only weight, only waist, only body fat %).
• Pull your latest measurement quickly for dashboards and check-ins.

Goals that keep you focused (without pressure)

Goals in OpenLift are designed to be simple and supportive:

• Create goals for any supported measurement type (weight, waist, body fat %, etc.).
• Set a target value, optional target date, and priority.
• See progress update as you log new check-ins.

OpenLift also prevents duplicate clutter by ensuring you can’t create multiple active goals of the same type at once—so your goals stay clear, not noisy.

Trends & simple predictions (for motivation, not hype)

For the metrics you track consistently, OpenLift can generate trend analysis over a time window (defaulting to recent history):

• Direction: increasing, decreasing, or stable
• Rate: how quickly it’s changing
• Consistency: how steady the pattern is
• Volatility: how “bouncy” the values are

You’ll also see lightweight projections such as:

• A next-month estimate
• A next three months estimate

Each comes with a confidence score based on how consistent your data has been.

If you only have 0–1 check-ins for a metric, OpenLift will ask you to log a bit more first—trend analysis needs at least two data points to be meaningful.

A quick “progress summary” snapshot

OpenLift can also generate a friendly overview of your recent measurement activity, including:

• Which measurement types you’ve been tracking
• Active vs achieved goals
• A simple direction indicator for recent trends

It’s meant to be a snapshot—something you can glance at and immediately feel oriented.

Progress photos (secure, simple, and optional)

Progress photos are here to help you see what the scale can’t.

OpenLift supports:

• Uploading progress photos (JPEG/PNG/WebP), with sensible file-size limits
• Common photo types like front, back, side, and pose
• Secure, expiring links for viewing photos
• Deleting photos when you no longer want them

Photos can be linked to a measurement entry so your visuals and metrics line up on the same timeline.

Privacy and ownership (built-in)

Your measurement data is personal. OpenLift enforces:

• Ownership checks so you can only access your own measurement entries, analytics, goals, and photos.
• Permission controls so features like analytics and photos can be enabled appropriately for your account.

Give it a try (low effort, high payoff)

If you’re not sure where to start:

1. Log a single weigh-in and add a short note (“morning, fasted”).
2. Add waist and chest once per week.
3. Take one progress photo per month in similar lighting.

Small, repeatable habits are what this feature is built for—and we’re genuinely excited to help you stay motivated as your progress accumulates.

Thank you for using OpenLift. We’re grateful you’re here—and we’re excited to keep adding tools that help you stay on track.
