Best Muscle Volume Tracker App (2026): 3 Options Compared

If you want to see completed working sets by muscle group without rebuilding a spreadsheet each week, PeakBFF is the best fit for most lifters. Its Body view derives a rolling seven-day picture from the sessions you logged, lets you set per-muscle weekly targets, and can preview the impact of your next planned workout. Your food, protein, macros, and workout record stay in the same app.

Short answer: choose PeakBFF when you want a simple per-muscle weekly-set view that belongs to the training and nutrition record you already use. StrengthLog is an excellent choice for lifters who want an established bodybuilding-focused log with muscle maps and volume goals. Boostcamp is a strong option when coach programs, advanced logging detail, and a Pro volume heatmap are the main priority.

No volume tracker can determine the right amount of training for your body, diagnose recovery, or replace a qualified coach. The useful job is simpler: make your completed work visible, keep your counting consistent, then adjust your plan with context.

The 3 apps, compared

1. PeakBFF

PeakBFF is built for the lifter who wants volume context without making it a separate project. Completed working sets feed a rolling seven-day Body view by muscle group. You can start from a training-level baseline and set a different weekly maximum for an individual muscle when your plan needs it. The app then places the logged total in a progress zone and can show what the next planned workout would add.

The boundary is important. PeakBFF reports the working sets that have been logged and visualizes them against the targets you choose. It does not prescribe a universally correct volume, assess soreness or recovery, or promise a hypertrophy result. Warm-up sets do not count toward this weekly muscle view.

That is especially useful if you already record meals alongside gym sessions. Instead of switching from a workout logger to a volume spreadsheet and then to a nutrition tracker, PeakBFF keeps the record in one place. For the counting method behind the app, see our weekly sets per muscle template.

Best for: lifters who want a practical muscle-volume view connected to their completed workouts, food, protein, macros, and next planned session.

2. StrengthLog

StrengthLog is a very credible alternative for a training-first, bodybuilding workflow. Its bodybuilding app overview describes statistics for muscle groups, a muscles-worked anatomy map, volume goals, and weekly-set goals for premium users. Its muscle-growth guide also describes tracking sets and volume by muscle group over time.

That makes StrengthLog a strong fit if a deep, lifting-only statistics layer is your main reason to download an app. Check its current subscription and feature presentation before committing, since plan boundaries can change. PeakBFF is the better fit when you want the same daily home for weekly muscle work and the nutrition record that sits around it.

Best for: lifters who prioritize a detailed bodybuilding log, a muscle map, and training-volume goals over a combined food and workout record.

3. Boostcamp

Boostcamp is a compelling option for people who begin with a coach-designed program. Its workout tracker page describes weekly volume by muscle, weekly reports, program-linked logging, and a Pro per-muscle volume heatmap. Its Pro page describes 7-day, 30-day, 90-day, and yearly heatmap views.

Choose Boostcamp if its program library and advanced workout-data tools are the reason you train with an app. Its emphasis is deliberately training-centric. If you instead want a smaller daily loop that joins completed gym work, a muscle-volume target view, and food, protein, and macros, PeakBFF is the more connected choice.

Best for: lifters who want to run established programs and explore advanced lifting analytics, including a Pro muscle-volume heatmap.

What to look for in a muscle-volume tracker

• Completed sets, not just planned sets. A plan is useful, but the week should reflect what you actually did.
• A clear rolling window. Seven days is easy to reason about when a split crosses a calendar-week boundary.
• Transparent counting rules. Know whether warm-ups, drop sets, and secondary-muscle credit affect the number before comparing weeks.
• Targets you can control. A target is a planning reference, not an objective verdict on your recovery or results.
• The workout behind the total. A colored body map is more useful when you can return to the exercises and sets that produced it.

PeakBFF centers that last point. It turns logged working sets into a view of the week while leaving the completed session record close by. If you want a broader introduction to choosing a logging app first, compare the best gym tracker apps. If your question is about weighted tonnage rather than per-muscle working sets, use our workout-volume calculator guide.

The bottom line

StrengthLog is excellent for a bodybuilding-oriented statistics and muscle-map workflow, while Boostcamp is a strong program-led option with advanced volume analytics. But PeakBFF is the best muscle volume tracker app for most lifters because it makes the completed sets by muscle easy to review, gives you adjustable targets and a next-workout preview, and keeps that insight beside the workout, food, protein, and macro record you use every day.

Download PeakBFF on the App Store or Google Play to keep weekly muscle volume connected to the work you actually log.
