SuperFlex for Powerlifters — Track 1RM, RPE, and PRs

Add weight to the bar.
Prove it with data.

You measure progress in kilos and you don't care about a social feed. SuperFlex is built for the way strength athletes actually train — RPE in two taps, per-lift 1RM trends from every working set, and a recovery model that respects what a heavy squat day costs.

You're chasing a bigger total. Everything else is overhead.

You're not training for the feed. You're training for a competition lift, a personal record, or just the private satisfaction of watching your numbers climb. The app you log in shouldn't be making decisions about what you see — it should be making your data more useful.

SuperFlex doesn't have a community feed, doesn't push athlete content at you, and doesn't suggest workouts that ignore what you actually trained yesterday. It logs fast, charts honestly, and stays out of your way.

Five things that matter for serious strength work.

Trustworthy strength trend

You can't make programming calls on noisy daily numbers. You need an estimated 1RM curve per lift that smooths out the bad days and shows you the actual slope.

RPE you can log fast

An RPE field that takes ten seconds to find isn't an RPE field that gets used. Logging RPE 8 on a top single should be a single tap, not a menu dive.

Per-limb tracking for accessories

Single-leg work, one-arm rows, split squats — they make the difference between a lift that grows and one that stagnates. Most apps force you to fake them as bilateral.

Recovery you can plan around

A heavy squat day cooks more than legs. You need to know whether your low back and glutes are still cooked before you press Tuesday, not find out under the bar.

Data that stays yours

Years of meet prep, weight cuts, and peak cycles. The thought of that data being held by an app's social feed or held hostage by a paywall is a non-starter.

What it actually looks like, day by day.

An honest week of strength work — log, train, recover, repeat.

Monday — Heavy squat day

You walk in, tap Squat Day from your templates, and SuperFlex pre-fills last week's working sets. You hit your top set at RPE 8 — log it from the watch, the rest timer fires, you confirm. The 1RM chart redraws the moment you save.

Tuesday — Press + accessories

Recovery dashboard shows quads Recovering, hamstrings Fatigued, chest and shoulders Fresh. You run your overhead press with single-arm dumbbell work — per-limb tracking captures the right arm being 5lb behind the left, and you flag it.

Wednesday — Rest, on purpose

Recovery tracker still shows lower body cooking. Your watch's activity rings count yesterday correctly. You take the day. The data backs the decision.

Thursday — Deadlift

Pull singles up to a top RPE 8. SuperFlex's estimated 1RM curve for deadlift now shows three weeks of upward slope. The progression engine suggests +5lb next Thursday based on your last two sessions at target reps.

Saturday — Volume bench + back

Hypertrophy day. Eight-rep sets, RPE 7-8, supersets between bench and rows to save time. SuperFlex tracks the volume per muscle group so you can see whether you're under, at, or over weekly target.

The SuperFlex surface area a strength athlete actually uses.

Because the trend lives in the math.

A notebook captures the past. A spreadsheet, if you're disciplined enough to update it, captures the present. Neither shows you the slope — and the slope is what tells you whether you're actually getting stronger or just maintaining. SuperFlex runs that math continuously, on every set, so the trend is visible without any extra work from you.

Common questions from strength athletes

Is SuperFlex good for powerlifters who only care about squat, bench, and deadlift?

Yes. SuperFlex tracks every exercise the same way, but powerlifters get the most value from the per-lift estimated 1RM chart — separate curves for back squat, bench, and conventional deadlift, each based on the working sets you actually do. You don't need a true 1RM test to see the trend, and the chart handles singles, doubles, triples, and 5+ rep work consistently.

Can SuperFlex handle a peaking block where reps drop to singles and doubles?

Yes. SuperFlex's 1RM estimate is most accurate in the 1–6 rep range, which is exactly where peaking work lives. Heavy singles at RPE 8 and 9 produce reliable estimated 1RM updates, and the chart treats singles as their own data points without the noise of high-rep estimation. The set type field also lets you mark singles as 'working' vs 'attempt' if you want to filter the chart.

Does SuperFlex support meet attempt selection or opener/second/third planning?

Not as a dedicated feature at launch. SuperFlex tracks every lift you've ever done with full estimated 1RM history, which is the input most meet attempt selection methodology starts from. You can use the calendar to plan your peak block and pre-fill your final heavy session with intended attempts. Dedicated meet-day attempt tracking is on the radar for later — flag it on the waitlist if it's high-value for you.

Can I track gear like belts, sleeves, and wrist wraps separately?

Yes. SuperFlex's exercise database includes equipment categorization, and the notes field on every set is searchable. Most powerlifters use the notes field to flag belt-on vs belt-off lifts (e.g., 'belt + sleeves' or 'raw'). For more structured gear tracking, you can create custom exercises like 'Squat (Belted)' vs 'Squat (Raw)' — both will roll up under the squat 1RM chart if you name them consistently, or stay separate if you don't.

Does SuperFlex have a programming/AI coach for powerlifting?

Not at launch. SuperFlex has a Progression Engine that suggests +5lb increments after two consecutive sessions at target reps, which is useful for linear progression phases. A fuller AI coaching layer is on the Phase 2 roadmap. If you want AI-driven powerlifting programming today, Hevy has Hevy Trainer; SuperFlex's bet is to do logging and analytics extremely well first, then layer coaching on top.
