Plan. Log. Compete.
Beat last week.
ForceLock makes progressive overload impossible to ignore. Track every set with surgical precision, watch your numbers climb on built-in charts, and stack up against your crew on the leaderboards.
7-day free trial. No card required. $5.99/mo or $59.99/yr after.
You can't overload what you don't measure.
Strength and hypertrophy are governed by one principle: progressive overload. If your numbers aren't climbing, you aren't growing. Most lifters fail this not because they don't work hard — they fail because they don't track with enough precision to know whether last week was actually harder than the week before.
Memory lies
Did you bench 185 × 7 last shoulder day, or 8? You don't know, so you redo it. That's a wasted week.
Plateaus go invisible
Without a baseline, plateaus look like 'just an off week' for months. By the time you notice, you've lost three.
You can't see growth
No charts. No PR list. No before/after. So even when you do progress, it doesn't feel like winning — and you stop showing up.
Everything a serious lifter needs. Nothing they don't.
Plan a split, log every set, see where you're winning and where you're slacking. Then come back next session and beat last week.
Today
Every exercise shows last session's top set right above the input — no flipping back to remember what to beat. Live timer, set-by-set logging, one-tap end.
Editable workout log
Every session forever. Tap any one to see the full breakdown — and edit it. Fix a typo, change a weight, add a forgotten set. Your history stays accurate.
Splits
Cycle (3 on / 1 off, 4-day, anything) or weekly (Mon-Sun). Per-exercise targets: sets, reps, RPE, drop sets, rest, tempo. Build your program once, run it for months.
Add exercises mid-session
Decided to throw in some curls? Hit Add Exercise mid-workout, pick from your library, log it inline. Never get locked into the day's plan.
Smart exercise typeahead
Type 'bench' and the canonical lifts surface — pick one and it auto-fills equipment. Or type a custom name to spin up your own. No duplicate clutter.
Skip days, edit duration
Felt rough? Tap "I was a pussy and didn't lift today" — the cycle still advances, the streak handles it cleanly. Fat-finger the time? Edit start and end on the log.
Calendar
See your whole training month at a glance. Each day color-coded by muscle group, with planned exercises one tap away.
Progression charts
Weight and reps over time, per exercise or per muscle group. Filterable date ranges. Watch the line climb — and notice immediately when it stalls.
Body weight + trend
Log today's weight from the Today tab in one tap. Full trend chart on Progression. Set lose/gain/hold goals with auto-tracked progress bars.
PR goals
Set targets like "Bench 315 × 1 by August 1." The day a logged set crosses the threshold, ForceLock detects it and stamps the goal achieved.
32+ achievements
100 / 365 / 1000 sessions. 600 lb single set. 5M lifetime volume. 365-day streak. Real milestones for the work you put in.
Progress pictures
Capture or upload progress photos with timestamps. Stored privately on encrypted object storage. Your transformation, on your timeline.
Train alone. Compete together.
A friend system that makes you actually want to show up. Codes instead of open search, a feed that's just lifters, leaderboards that mean something.
Strava-style feed
Your friends' last 4 days of workouts. Stats tiles, exercise breakdown, 🔥 reactions. Friends-only — no influencers, no ads.
Activity leaderboards
Lift Streak, Sessions This Week, Volume This Week. See who's grinding and who's slacking — including yourself.
Strength leaderboards
Heaviest set on 12 free-weight compounds — bench, squat, deadlift, OHP, and more. Toggle between raw lb and per-bodyweight ratio so the lighter lifter can compete on equal footing.
Schedule workouts
Pick a gym, a time, who you want there. Invitees get a push, RSVP from their phone, and the workout shows on everyone's Today tab the day of.
Push notifications
Friend request, accepted invite, workout reminder — all on your phone, all opt-in. Works for installed PWAs (iOS 16.4+) and any Android browser.
Privacy you control
Three independent toggles: allow friends, show in gym lists, show on leaderboards. Codes-only discovery — no random adds. Friends without showing up on boards is a real config.
“Progressive overload is the single biggest predictor of both strength and hypertrophy gains. The lifters who track and push their numbers — week over week, set over set — are the ones who actually grow.”
Other apps were built for fitness influencers.
ForceLock was built for lifters.
A feed that's just your crew, leaderboards that reward real numbers, and the cleanest possible read on whether the work you put in last week is actually paying off this week.

Real progressive overload math. Estimated 1RM (Epley), top-set climb, group-level growth Δ% — the stats coaches actually use.
Friends-first, not random. Discovery is by 8-character code, exchanged in person. No open username search, no random adds, no spam.
Mobile-first, gym-ready. Designed to be tapped through with one thumb between sets, not poked at on a tablet at home. Installs as a PWA on iOS and Android.
