What is the best app for running Jim Wendler's 5/3/1 program?

Gladiator Lift is the most complete 5/3/1 app available. It calculates your training max automatically, tracks AMRAP rep PRs, handles automatic TM progression every 4 weeks, and supports all major variants including BBB, FSL, and Triumvirate.

How does Gladiator Lift handle the 5/3/1 training max?

When you set up a 5/3/1 program in Gladiator Lift, you enter your 1RMs and the app calculates your training max at your chosen percentage (typically 85–90%). After each 4-week cycle, it automatically prompts you to increase the TM by the standard 5 lb (upper) or 10 lb (lower) increments.

Can Gladiator Lift track 5/3/1 AMRAP sets and rep PRs?

Yes. Every AMRAP set in Gladiator Lift has a rep counter that displays a PR badge when you beat your previous rep record at that weight. Your full AMRAP history is stored and viewable in the lift's performance log.

Does Gladiator Lift support 5/3/1 Boring But Big?

Yes. Gladiator Lift includes BBB as a built-in 5/3/1 variant. The 5×10 back-off sets are automatically calculated at 50% of your training max, and you can log all accessories within the same session template as your main lift work.

What should I do if my 5/3/1 progress has stalled?

Gladiator Lift's analytics can diagnose common 5/3/1 stalls. If your AMRAP rep counts on Week 1 sets are below 5 for two consecutive cycles, the app flags a likely TM-too-high issue. You can also review deload compliance and accessory volume balance in the muscle group chart.

Best Apps for Running the 5/3/1 Program

Quick Answer: Gladiator Lift is the best app for running Jim Wendler's 5/3/1, offering built-in training max calculation, AMRAP set tracking with rep PR alerts, automatic cycle progression, and support for all major 5/3/1 variants including BBB, FSL, and Triumvirate — no spreadsheet required.

Jim Wendler's 5/3/1 program has earned its reputation as one of the most reliable strength training systems ever developed. The premise is simple: build your training around four big lifts (squat, bench, deadlift, overhead press), progress conservatively based on a training max, and never miss reps. The approach is humble, sustainable, and backed by decades of results in gyms worldwide.

But despite its conceptual simplicity, 5/3/1 has considerable administrative complexity. You're tracking training maxes per lift (which update every 4 weeks), calculating percentages for three distinct rep schemes across a monthly cycle, managing an AMRAP set, recording your rep PR history, and potentially running one of a dozen variants with different accessory schemes. Managing all of this in your head — or even in a standard notes app — is inefficient and error-prone.

The right app makes 5/3/1 nearly automatic. This guide covers what to look for, and which apps do it best.

Understanding 5/3/1's Structure Before Choosing an App

Every 5/3/1 app lives or dies by how well it handles the program's core mechanics. Here's what your app must support:

Training Max (TM) Calculation — the TM is 85–90% of your 1RM and serves as the base for all calculations. It increases by 5 lb per cycle for upper body lifts and 10 lb for lower body lifts. Your app must track this separately from your 1RM. Weekly Percentage Waves — the classic 5/3/1 percentages are:

Week 1: 65% × 5, 75% × 5, 85% × 5+
Week 2: 70% × 3, 80% × 3, 90% × 3+
Week 3: 75% × 5, 85% × 3, 95% × 1+
Week 4 (Deload): 40%, 50%, 60% × 5

AMRAP Tracking — the final set of each main movement is an AMRAP. Recording your rep count and tracking rep PRs at each weight is crucial for gauging progress. A good app alerts you when you've set a new rep PR. Variant Support — Wendler has released numerous variants (Beyond 5/3/1, 5/3/1 Forever, BBB, FSL, etc.). Your app should support at least the major accessory schemes.

Gladiator Lift for 5/3/1 Programming

Gladiator Lift handles 5/3/1 natively with a dedicated program template. When you set up a 5/3/1 program, you enter your current 1RM (or an estimated max) for each of the four main lifts, and the app calculates your starting training max, all weekly percentages, and your full first cycle — ready to log on day one.

What sets Gladiator Lift apart from generic apps running 5/3/1 via manual templates:

Automatic TM progression — at the end of each 4-week cycle, the app prompts you to confirm the standard TM increase (or adjust it based on your AMRAP performance)
AMRAP rep PR tracking — every AMRAP set gets a dedicated rep counter with a visual PR badge when you beat your previous best
Joker set support — log optional Joker sets (additional top sets at 105%, 110%, 115%) without disrupting the main progression record
First Set Last (FSL) tracking — log FSL back-off sets with automatic weight calculation based on Week 1 percentage
Boring But Big (BBB) accessory logging — 5×10 accessory sets at 50–60% with automatic weight calculation from TM

Setting Up 5/3/1 in Gladiator Lift Step by Step

Open the Programs tab and select "5/3/1" from the template library
Enter your 1RMs for squat, bench press, overhead press, and deadlift
Choose your TM percentage — 85% is standard for most lifters; 90% for more experienced
Select your variant — choose from standard 5/3/1, BBB, FSL, Triumvirate, or 5s PRO
Set your training days — assign which main lift runs each day of the week
Configure accessory pools — select your preferred accessories for each session
Begin Week 1 — all weights are pre-calculated and ready to log

The setup takes less than 5 minutes. From that point, every session shows you exactly what to lift with no math required.

Comparing AMRAP Tracking Across Apps

App	AMRAP Tracking	Rep PR Alerts	Auto TM Progression	Variant Support
Gladiator Lift	Yes	Yes	Automatic	5+, BBB, FSL, Triumvirate
5/3/1 Wendler App	Yes	Basic	Manual	Limited
Strong	Manual entry	No	Manual	Manual templates
Hevy	Manual entry	No	No	Manual templates
JuggernautAI	AI-managed	Partial	Automatic	Limited

The dedicated 5/3/1 Wendler App covers the basics but hasn't been updated significantly in recent years and lacks modern analysis features. Gladiator Lift provides the same dedicated 5/3/1 support with a more complete feature set and active development.

Using Estimated Max Formulas to Set Your Training Max

If you don't have a recent 1RM test to base your TM on, Wendler recommends starting conservatively — and Gladiator Lift supports several estimation methods:

Epley Formula: 1RM = Weight × (1 + Reps/30) Brzycki Formula: 1RM = Weight / (1.0278 − 0.0278 × Reps)

For a 225-lb bench for 5 reps:

Epley: 225 × (1 + 5/30) = 225 × 1.167 = 262 lb estimated 1RM
TM at 85%: 223 lb

Gladiator Lift applies these formulas automatically based on your best logged set if you don't have a standalone max test. This is particularly useful for new lifters starting 5/3/1 without a testing baseline.

Managing 5/3/1 Variants and Long-Term Programming

One of the most powerful aspects of 5/3/1 is its longevity. Wendler's system is designed to run for years, not weeks. That means your app needs to handle long-term TM progression, variant switching between cycles, and program history.

Gladiator Lift maintains a full cycle log for each 5/3/1 program, showing you:

TM progression over time per lift
Best AMRAP rep count at each weekly percentage
Estimated 1RM trend derived from AMRAP performance
Volume load per session over time

When you're six months into 5/3/1 and want to switch from BBB accessories to FSL, you can update the accessory template without losing your main lift progression history. The program continues as a continuous record rather than restarting.

When 5/3/1 Stops Working — and How Your App Can Help

Most 5/3/1 stalls happen for one of three reasons: training max set too high, insufficient deload compliance, or poor accessory selection for your weak points. Gladiator Lift's analytics make all three diagnosable:

TM too high shows as AMRAP rep counts below 5 on Week 1 sets. The app flags this pattern after two consecutive cycles. Deload skipping is tracked in the session log — if Week 4 weights aren't being logged at the specified percentages, the app shows an alert. Accessory balance is visible in the muscle group volume chart — if your posterior chain volume is half your anterior chain volume, you know where the imbalance lies.

Armed with this data, you can make evidence-based adjustments rather than guessing why progress has stalled.
