Programs

Big Brain Barbell supports three program types, each designed for different training goals. This page explains how each program type works, how to create one, and how to manage your programs over time.

Strength Programs

Who it's for

Strength programs are built for lifters whose primary goal is getting stronger on specific compound lifts. Whether you're a competitive powerlifter preparing for a meet, or a recreational lifter who wants to push your squat, bench, and deadlift numbers higher, Strength is the right choice. It's also ideal for anyone who thrives on structured, periodized training with clear phases and measurable progress.

How it works

Strength programs use phase-based periodization to systematically build maximal strength. Training cycles through three distinct phases, each with a specific purpose:

1. Hypertrophy — Higher volume with moderate intensity. This phase builds the muscle mass and work capacity that serve as the foundation for later strength gains. Expect more sets and reps at lower percentages of your max.
2. Strength — Moderate volume with higher intensity. This phase converts the muscle you built during hypertrophy into usable strength. Sets get heavier while rep counts decrease.
3. Peaking — Low volume at maximum intensity. This phase is about expressing your strength. You'll handle the heaviest loads with minimal volume, allowing your body to fully realize its strength potential.

The app suggests transitions between phases based on your progress, so you don't need to plan when to switch. See the Phase Lifecycle section below for details on how transitions work.

Goal types

Strength programs use exercise-focused goals organized around six fundamental movement patterns. Each goal targets a specific movement category, and the app selects appropriate exercises based on your available equipment:

• Squatting — Back Squat, Front Squat, Goblet Squat, and other squat variations
• Hinging — Deadlift, Romanian Deadlift, Trap Bar Deadlift, and other hip-hinge movements
• Horizontal Push — Bench Press, Dumbbell Press, Push-ups, and other pressing movements
• Horizontal Pull — Barbell Row, Cable Row, Dumbbell Row, and other rowing movements
• Vertical Push — Overhead Press, Dumbbell Shoulder Press, and other overhead pressing movements
• Vertical Pull — Pull-ups, Lat Pulldown, and other vertical pulling movements

You choose which movement patterns to include in your program. A well-rounded strength program typically includes goals from all six categories, but you can focus on fewer if you prefer.

Bodybuilding Programs

Who it's for

Bodybuilding programs are designed for lifters focused on aesthetics and muscle development. If your primary goal is building a well-proportioned physique, adding size to lagging muscle groups, or simply training for muscle growth without worrying about how much you can lift on any particular exercise, Bodybuilding is the right choice.

How it works

Bodybuilding programs focus on pure hypertrophy — every week is dedicated to maximizing muscle growth. Unlike Strength programs, there are no periodization phases. Instead, the app continuously adjusts volume and exercise selection to keep driving muscle growth week after week.

The adaptation system monitors your session feedback, recovery, and performance to fine-tune the training stimulus. If you're recovering well, volume may increase. If you're showing signs of fatigue, the app dials things back. This ongoing auto-regulation replaces the need for distinct training phases.

Goal types

Bodybuilding programs use muscle-focused goals targeting 15 individual muscle groups. This gives you precise control over which muscles receive direct training volume:

You select which muscle groups to include as goals. Each goal receives dedicated training slots in your weekly sessions. You can prioritize lagging body parts by including them as goals while leaving well-developed muscles out, or include everything for balanced development.

Powerbuilding Programs

Who it's for

Powerbuilding is for lifters who want the best of both worlds — the structured strength progression of a Strength program combined with the targeted muscle development of a Bodybuilding program. If you care about getting stronger on your main lifts but also want to build a well-rounded, muscular physique, Powerbuilding is the ideal choice.

How it works

Powerbuilding is a hybrid approach that combines both goal types into a single program:

• Exercise-focused goals cycle through periodization phases just like Strength programs. Your main compound lifts (squats, deadlifts, presses, rows) progress through Hypertrophy, Strength, and Peaking phases for systematic strength gains.
• Muscle-focused goals remain constant throughout, just like Bodybuilding programs. Your accessory work consistently targets specific muscle groups for ongoing hypertrophy.

This means your training sessions include heavy compound work that gets progressively heavier over time, alongside accessory exercises that keep driving muscle growth regardless of what phase your main lifts are in.

Goal types

Powerbuilding programs support both exercise-focused and muscle-focused goals. During program creation, you'll select goals from both categories:

• Exercise-focused goals — Choose from the six movement patterns (Squatting, Hinging, Horizontal Push, Horizontal Pull, Vertical Push, Vertical Pull). These follow phase-based periodization.
• Muscle-focused goals — Choose from the 15 muscle groups (Chest, Upper Back, Biceps, etc.). These remain in a constant hypertrophy state.

A typical Powerbuilding setup might include 3-4 exercise-focused goals for your main lifts and 4-6 muscle-focused goals for accessory work, but you can customize this however you like.

Program Creation Wizard

Creating a program in Big Brain Barbell is a guided process. The creation wizard walks you through each step to build a program tailored to your goals, schedule, and equipment.

Step 1: Choose a program type

The first screen presents the three program types: Strength, Bodybuilding, and Powerbuilding. Each option includes a brief description to help you decide. Tap the one that best matches your current training goals.

Step 2: Set training days per week

Next, choose how many days per week you want to train. Big Brain Barbell supports anywhere from 2 to 6 training days. The app uses this to distribute your goals across the week, ensuring balanced workload and adequate recovery between sessions that target the same movement patterns or muscle groups.

Step 3: Select goals

The goal selection screen shows the available goals for your chosen program type. For Strength programs, you'll see the six movement patterns. For Bodybuilding, you'll see the 15 muscle groups. For Powerbuilding, you'll see both.

Tap each goal you want to include in your program. The app ensures your selected goals can fit within your chosen number of training days. If you select more goals than can be reasonably accommodated, the app will let you know.

Step 4: Review and create

The final step shows a summary of your selections: program type, training days, and all selected goals. Review everything and tap Create to generate your program.

Big Brain Barbell then automatically generates your first week of training sessions, selecting appropriate exercises based on your goals and available equipment. Your training calendar will immediately populate with your new sessions.

Phase Lifecycle

Phase-based periodization is a core feature of Strength and Powerbuilding programs. Understanding how phases work helps you get the most out of your training.

The three phases

Every Strength program (and the exercise-focused goals in Powerbuilding programs) cycles through three phases in order:

1. Hypertrophy (Phase 1) — The foundation-building phase. Training volume is high with moderate loads. Rep ranges are typically higher (8-12+ reps), and the focus is on accumulating training volume to build muscle mass and work capacity. This phase prepares your body for the heavier work ahead.
2. Strength (Phase 2) — The conversion phase. Volume decreases while intensity increases. Rep ranges drop (4-6 reps), and loads get heavier. The muscle mass built during hypertrophy is now being trained to produce maximum force.
3. Peaking (Phase 3) — The realization phase. Volume is minimal while intensity is maximal. Rep ranges are very low (1-3 reps), and you're handling near-maximal loads. This is where you express your full strength potential.

Guided phase transitions

When you've been in a phase for its recommended duration (typically 6 weeks), Big Brain Barbell suggests moving to the next phase during weekly generation. You can accept the suggestion and transition, or continue in your current phase if you prefer. The choice is always yours.

When you accept a phase transition, your upcoming training sessions will reflect the new phase's rep ranges, intensity levels, and volume targets.

Manual phase transitions

You can also manually change your training phase from the program overview screen at any time. This is useful if you have a specific timeline in mind — for example, if you want to peak for a competition on a certain date, or if you feel ready to move on before the app suggests the transition.

Phase cycling

After completing a Peaking phase, the cycle resets back to Hypertrophy. This continuous cycling ensures long-term progress — each new Hypertrophy phase builds on the strength gains from the previous Peaking phase, creating an upward spiral of development over months and years.

Equipment-Aware Exercise Selection

When generating programs, Big Brain Barbell filters exercises based on your equipment configuration. If you don't have a barbell, you won't be prescribed barbell exercises. If you only have dumbbells, the app builds your program around dumbbell movements.

This filtering happens both during initial program creation and every time new weekly sessions are generated. You can update your equipment at any time in Settings, and new sessions will reflect the changes.

Managing Programs

One active program at a time

Big Brain Barbell supports one active program at a time. This keeps your training focused and ensures the adaptation system has clear, consistent data to work with. If you want to switch your training focus, you'll need to archive your current program before creating a new one.

Program overview

You can view your active program's details at any time from the Programs tab. The overview shows your program type, current phase (for Strength and Powerbuilding), all selected goals, and training days per week.

Archiving a program

When you're ready to move on — whether you've completed a training cycle, want to try a different program type, or just need a change — you can archive your current program. Archiving does not delete any data; your training history and performance records are preserved.

Creating a new program

Once your previous program is archived, you can create a new one using the Program Creation Wizard. Your exercise history carries forward, so the app already knows your strength levels and can make informed exercise selections for your new program from day one.
