01
Understand Your Training
Every completed set adds context. Strength records exercises, weights, repetitions, and completed workouts so Aristeia can evaluate how training is developing.
Strength features
One connected system for training with direction.
Plan the work. Train with context. Understand what happened, then carry that information forward.
Plan
Structure that starts with your training.
Strength supports the way you already think about training. Build recurring programs, keep reusable workout structures nearby, and prepare a workout before it is time to start.
- ProgramsOrganize training days and the work ahead.
- Workout TemplatesReturn to sessions you use often without rebuilding them.
- Gym ProfilesKeep your training environment in view when planning.
Train
Stay with the work in front of you.
The workout is where training becomes real. Strength keeps relevant history close, supports the ways sessions are structured, and leaves room to adapt when a session changes.
- Keep context visibleReview previous performance while recording the work in front of you.
- Adapt when training changesUse substitutions and workout drafts without losing the thread of the session.
- Support the work you doLog standard sets, pyramids, top and backoff work, AMRAPs, and supersets.
- Stay focused between setsUse rest timing, Live Activities, and Dynamic Island to keep an active workout close.
Aristeia Intelligence
Training intelligence grounded in your performance.
Most workout trackers tell you what you did. Aristeia helps you understand what to do next. Built into Strength, it evaluates relevant recorded training history, identifies meaningful performance patterns, and provides practical guidance for workout progression.
02
Recognize Meaningful Patterns
Progress is not always linear. Aristeia evaluates relevant patterns, including repeated difficulty meeting training targets, to identify when an adjustment may be useful.
03
Recommend Your Next Move
When sufficient performance evidence supports an adjustment, Aristeia can recommend changes to exercise progression and explain its reasoning. You choose whether to apply or ignore it.
A recommendation, in context
Practical guidance, not guesswork.
When repeated sessions fail to meet a training target, Aristeia can recognize the pattern and recommend an appropriate adjustment.
A conventional workout tracker records what happened. Aristeia helps the athlete decide what to do next.
Aristeia informs the decision.
You make it.
Progress
Training history becomes useful context.
Look back at individual sessions, step back to see longer-term change, and review how your training is distributed. Strength helps make the record of your work easier to use.
- Sessions and recordsReview workout history and personal records in context.
- Change over timeFollow estimated strength, performance trends, and bodyweight history.
- Training distributionSee body-region coverage alongside the work you have completed.
Share
Share your workouts. Exchange your programs.
Strength lets you share completed workouts, exchange reusable training programs, and send workout templates to other Strength athletes.
Completed workouts
Share the session.
Turn a completed workout into a visual performance card for the iOS Share Sheet. Cards can summarize exercises, sets, training volume, duration, and qualifying personal records.
Training programs
Exchange the plan.
Export a structured program as a .strengthshare file. Another Strength athlete can open it, preview it, and choose Add; the imported program begins as a draft without changing active programming.
Workout templates
Pass on the structure.
Exchange reusable workout templates in the same Strength sharing format—without transferring personal training history. Template limits may apply.
Data portability
Your training history comes with you.
