Train smarter
Because a strong foundation is key to everything else. Every program is personalised just for you based on where you are now, and where you want to be.
Want intervals, circuits, or engine work in the mix? Just say the word. Zena programs it around your lifting days instead of leaving you to bolt on a separate cardio app.
Not a vague reminder to stretch after you lift. Add personalised mobility sessions, built around what you're training and what's tight.
Sleep, HRV, resting heart rate — before every session, so the balance between hard training and easier work isn't something you have to guess at.
How it works
Zena will build a program based on your equipment, recent performance and how often you want to train.
Track your sessions, log your weights, reps and efforts. Zena automatically calculates your working weights and progression, so you can focus on the lift instead of the math.
Track your progress with detailed insights and analytics, so you can see how far you've come and what to focus on next.
Recover Faster
Tight hips after squat day. A shoulder that needs range of motion before a pressing block. Zena can build dedicated mobility and stretching sessions around exactly what you're training — not a generic five-minute stretch tacked onto the end of a lift.

Health Data Integration
Every morning, Zena reads sleep, HRV, resting heart rate, and a proprietary waking heart rate signal from Apple Health and turns it into a single readiness score — Ready, Moderate, Ease back, or Rest — with an AI narrative explaining why.
That score isn't just a dashboard number. It's the same signal behind whether today's strength session pushes for a new working weight, whether a conditioning day stays high-intensity or eases toward threshold work, and whether mobility takes priority over anything harder.
See your progress
Working weight, estimated one-rep max, and rep volume are tracked for every lift, so "am I actually getting stronger" has a real answer instead of a guess based on how a session felt.
Personal records get called out the moment you hit them. Beyond single lifts, Zena also tracks consistency over time and progress toward specific weight goals, with a read on whether you're actually on pace to hit them.
Why it's not strength-only
Progressive overload, enough recovery, and consistency over time remain the core of every program Zena builds. But a lot of women serious about lifting also want to move well, have some conditioning capacity, and not feel stiff and locked up between sessions.
Conditioning built around your training builds real work capacity without competing with your lifting for recovery. Mobility work targeted at what you're actually training protects the joints doing the heavy lifting and can extend your range of motion where it matters for the lift itself.
Zena is built around creating a strong foundation through strength training. Conditioning, mobility, and stretching are there to add when — and if — a more balanced week is what you're actually after.
Common questions
Most fitness apps offer you a range of pre-created programs. Zena creates individual strength training programs, personalised to your goals, your equipment, and your recent performance. You can also add conditioning, mobility, and stretching to create a more balanced program. An AI layer reads your recovery (sleep, HRV, resting heart rate) before every session so it knows when to push and when to ease off.
Yes. Tell Zena you want conditioning in the mix — and the type of conditioning you prefer — and it builds those sessions into your program around your lifting days, sized to the training block you're in rather than left as a generic add-on.
No — strength programming works exactly the same either way: progressive overload, real working weights, and automatic progression based on what you've actually logged, not a rigid percentage rule. Conditioning and mobility get built in around that core; they don't change how it's calculated.
Yes. Zena can generate dedicated mobility and stretching sessions based on what you're training and where you need range of motion — hips after a heavy squat day, shoulders before a pressing block — rather than a five-minute stretch tacked onto the end of a lift.
Strength only is completely fine — it's the default, and always the priority in every program Zena builds. Conditioning and mobility are there if you want a more balanced week, not a requirement.
Not if it's programmed properly, which is the point. Zena sizes conditioning and mobility work around your lifting days and factors your recovery data into the whole week, not just the strength sessions — so a hard conditioning day doesn't quietly undercut the squat day two days later.
Every morning, Zena reads sleep, HRV, resting heart rate, and a proprietary waking heart rate signal from Apple Health and turns it into a single readiness score, with a plain-language read — Ready, Moderate, Ease back, or Rest — plus an AI narrative explaining why. It's the same signal behind whether today's session pushes for a new working weight, holds steady, or shifts toward something lighter, whether that's strength, conditioning, or mobility.
Both. Zena explains recommendations in plain language rather than assuming you already know every term. Whether you're getting back into training after time off or you've been lifting for years, the program builds around your current strength and goals, not a fixed starting point.
Zena comes with a free 2-week trial, so you can build your own program — strength only, or with conditioning and mobility mixed in — and see how it fits before deciding if it's right for you.
Yes. If you've already got a strength program from a trainer, a PDF, or a spreadsheet, import it — Zena adds the coaching layer on top: tracking, automatic progression, recovery-based adjustments, and conditioning or mobility sessions built in around it, so you're not maintaining a separate app for the rest of your week.
No leaderboards. No benchmarks against anyone else. Progress is measured against one person only — you.
