Everything the Stream does after you press Start.

DELTASTREAM computes your next workout, adapts to your recovery and body-composition goals, and coaches every set — not from templates, but from your data.

Adaptive Training Engine

A program that thinks ahead.

01
Your Next Workout Is Always Ready
Open the app and your next session is waiting — exercises, sets, reps, and loads, all chosen for you. No program to finish, no plan to restart.
02
Every Set Is Calculated For You
You never have to figure out what weight to use or how many reps to aim for. The app knows your history and picks the right targets for today.
03
It Adjusts Between Sets
Crushed that last set? Fell short? The app recalculates your next set on the spot — not at the end of the workout, right now.
04
Weights You Can Actually Load
Targets snap to the real plates and dumbbells in your gym. You'll never see "press 73.2 lbs."
05
Smart Starting Weights for New Exercises
Try a new exercise and the app already has a sensible starting weight based on what you can do on similar movements.
06
It Gets Better at Predicting You
The more you train, the more accurately the app dials in your targets — it learns where it over- or under-shoots and self-corrects.
07
It Learns Your Gym
Correct a weight suggestion once, and the app remembers what's available on your rack for next time.
08
Built-In Variety
Exercises rotate automatically so you're not doing the same routine every week, but your progression still carries through.
09
Plateau Breaker
Stuck on a muscle group? The app detects the stall and shifts training volume where it's needed most to get you moving again.
10
Knows How Long You'll Be
See an estimated session duration before you start — and it gets more accurate the more you train.

Recovery & Fatigue Management

Knows when to push, knows when to pull back.

11
Built-In Recovery Intelligence
The app tracks fatigue for each muscle group and automatically dials back targets, schedules lighter sessions, or skips movements when you need recovery — before you get hurt.
12
Quick Soreness Check-Ins
A fast tap during rest tells the app how your muscles are feeling, so it can adjust the rest of your session accordingly.
13
One-Tap Effort Logging
After each set, tap Easy, Solid, or Brutal. That's it — the app uses it behind the scenes to fine-tune your progression and recovery.

Body Composition & Phase Planning

A real plan for your body.

14
Goal-Driven Phase Planning
Tell the app what you want — lose fat, build muscle, or both — and it maps out the phases to get you there, switching between cut, maintain, and build automatically.
15
See How Far You Have to Go
A clear visual showing how close you are to your target body composition, with a timeline that updates as you progress.
16
Weigh-Ins That Actually Do Something
Log your weight and the app recalculates — adjusting your calorie estimates and phase plan in real time, not just adding a dot to a chart.
17
Training Adapts to Your Phase
Cutting? The app shifts your training toward strength preservation. Building? It leans into hypertrophy. You don't have to manage this — it happens automatically.
18
No Endless Diets
Long cuts are broken into manageable blocks with built-in maintenance periods. The app enforces the breaks your body needs.
19
Just Want to Lift?
Skip the body comp goals entirely. The training stream keeps running with pure strength progression — no planning required.

Coaching & Education

A coach that knows you.

20
Pick Your Coach's Personality
Choose between different coaching voices — tough love, analytical, encouraging, or laid-back. The advice stays the same; the delivery matches you.
21
Choose How Much Coaching You Want
Want just the essentials? Go Focused. Want deeper explanations and more personality? Switch to Guided. Change anytime.
22
Learn While You Rest
Between sets, the app surfaces bite-sized lessons — form tips, training science, philosophy — relevant to what you're doing right now and fresh every time.
23
Get Smarter Over Time
Your coach teaches training principles progressively through conversation — not a textbook dump, but a dialogue that meets you where you are.
24
Ask Anything, Anytime
Chat with your coach about your program, your progress, or how the app works — and get answers grounded in your actual training data, not generic advice.
25
Your Coach Reaches Out First
Recovery nudges, milestone celebrations, training insights — the coach starts conversations when it has something worth saying.
26
Feedback After Every Set
A quick note after each set tells you what happened, what changed, and what to think about on the next one.

Program Customization

Your program, your way.

27
Prioritize What Matters to You
Rank the muscle groups you care about most and the app builds every session around your priorities — not a cookie-cutter split.
28
One-Tap Profiles
Pick from 11 goal-specific starting templates — Bikini Body, Strength, General Conditioning, and more — then customize from there.
29
Choose Your Rep Style
Straight sets, pyramid, or reverse pyramid — pick the style you like and the app handles all the math behind it.
30
Alternate or Group Your Exercises
Prefer supersetting different muscle groups or hammering one at a time? Toggle between styles to match how you like to train.
31
Cap Your Weekly Volume
Short on time or managing fatigue? Set a weekly ceiling and the app redistributes your training within that budget.
32
Swap Exercises on the Fly
Someone's on your bench? Swap to an alternative mid-workout and the app retargets your weights instantly — no manual math.

Performance Tracking

See what's working.

33
Muscle-by-Muscle Progress
After each session, see exactly how each muscle group performed compared to last time — with clear percentage changes.
34
Strength Trend Charts
Visual charts show whether each muscle group is trending up, flat, or down — with a confidence rating so you know when to trust the trend.
35
Your Power Rating
One number that captures your overall strength level, from Beginner to Peak — watch it climb over weeks and months.
36
Automatic PR Tracking
The app catches every personal record — by set, exercise, and muscle group — and tracks your streaks of consecutive-session PRs.
37
The App Tells You What It Learned
After each session, a plain-English note explains what the system picked up about your performance and how your next workout will change because of it.
