Been using it about 4 months. I used to spend Sunday nights putting my week together and now I just open it. Took me a couple weeks to trust it wasn’t going to have me squatting three days in a row.

Came back from a shoulder thing and honestly I was scared to press anything overhead. It had me on light DB work for what felt like forever. I was annoyed at the time. I’m pressing again now.

I’m on the road maybe two weeks a month and the travel setting is the only reason I’ve kept a streak going. Wish you could set it in advance instead of the morning of.

It’s really easy to use Charles and it does much more than just create workout plans. It gets to know me and gives personalized, dynamic guidance based on my needs. I especially love that it also takes health condition into account.
02 / THE PROBLEM

Stop guessing.
Start progressing.

Most people walk into the gym and do the same machines every week. No plan, no progression, no results. Other apps don't fix that. They log what you did, or guess your next set. None of them own the plan.

I do. I write your whole programme, read every session you log, and adjust what comes next after each one. Travelling, a packed week, coming back from pain, the plan follows your life. You keep getting stronger without ever thinking about what to train.

03 / METHOD

What I do.

01

A Plan That
Progresses

A real plan with a destination, not random workouts. Some weeks build you up, some push you hard, on purpose. After every session I look at what you did and adjust what comes next.

02

Pain-Aware
Training

Tell me something hurts and I swap the movement for a safer one, right there in your session. You never push through pain.

03

Built For
Your Gym

I build the plan around the kit your gym actually has, with real exercises and full video for every one. Never a generic template.

05 / HOW

Three steps.

01

Assess

Answer a dozen quick questions about your strength, training history, and goals. I learn how you train before I programme a single set.

02

Programme

I map out your months ahead, with the right exercises matched to your assessment and each phase building on the last.

03

Train

Follow the plan. Log your sets. After every session I read how it went and shape the next one, adapting as I learn what works for you.

06 / LIFE HAPPENS

Life happens.
The plan keeps up.

01

A Busy
Week

Some weeks are packed. Tell me you are short on time and I give you a shorter session that still moves you forward, rather than half of a long one you will not finish. Showing up short beats not showing up at all.

02

On
Holiday

Holiday Mode gives you quick sessions built around whatever your hotel gym has, so you never fully stop. When you are home, your programme picks up right where it left off.

03

Coming
Back

Pain, an injury, a few weeks off. Tell me what happened and I ease the load, swap the risky movements, and build you back up without losing the thread.

FAQ

About training

How many days a week should I train?

For most people two to four hard sessions a week is the sweet spot, and your muscles actually grow while you rest, not just while you lift. So more days is not automatically better. I build your plan around the number of days you can realistically keep, and I space the work so each muscle recovers before you hit it again. The best schedule is the one you actually stick to.

How long should a gym workout be?

Under an hour is enough for almost everyone, and forty five focused minutes often does more than a distracted ninety. What changes your body is how hard you train, not how long you stay. I keep your sessions tight, and the built in rest timer keeps you honest between sets, so your time in the gym is spent training instead of scrolling.

Should I train if my body hurts?

It depends where it hurts. Normal muscle soreness is safe to train around, and gentle movement often helps it fade. Sharp or joint pain is different and means back off. Tell me where it hurts and I do two things: I swap the movements that aggravate it for ones that do not, and if you need it I build a dedicated recovery phase into your plan so you come back stronger. You never push through pain to keep a plan happy.

How much weight should I lift as a beginner?

Lighter than your ego wants. The right weight is one you control for every rep with a couple left in the tank, not the most you can survive. I set your starting weights from a short assessment and then adjust them every session based on what you actually logged, so they get accurate fast. If a weight ever feels wrong, change it and I build that into what comes next.

How do I build muscle at the gym?

You give the muscle a reason to grow, then feed and rest it so it can. In the gym that means training it hard enough and adding a little over time, not doing the same thing forever. I handle that half: the right exercises, sets, and weights, getting harder in the right places so you keep progressing instead of stalling. It works the same whether you are 25 or 65.

How long until I see results from lifting?

There is no exact date, and anyone who promises one is selling something. The usual order is that the weight on the bar moves first, often within a few weeks, then how your clothes fit, and the mirror comes last. Show up, log your sessions, and I make sure each one builds on the last so the progress keeps coming.

About Charles

Is a workout app better than a personal trainer?

For the part most people actually need, the plan, yes, and for a fraction of the price. A coach who writes and adjusts your programme runs $150 to $300 a month. I do exactly that for $19.99: I write your full plan, read every session, and change what comes next. What a trainer adds is eyes on your form in the room, so the honest answer is I replace the programming, not the spotting, and I work well next to a coach if you have one.

How is Charles different from other workout apps?

Most apps log what you already did or hand you a fixed template. I decide what you do next and own the plan. I write your full programme, read every session you log, and adjust it after each one, so it keeps fitting you as you get stronger, get injured, or travel. It is the difference between a notebook and a coach.

Does Charles adjust my plan as I get stronger?

After every single session. I read what you lifted and how it felt, then shape what comes next, adding load and changing exercises through phases that build on each other. That is how you keep progressing instead of stalling on the same routine, and it is the work you would normally pay a coach to do by hand.

Does Charles work with my gym's equipment?

Yes. You tell me the equipment your gym has, from a big commercial chain to a smaller local one, and I only ever programme exercises you can actually do there, each with a full video. If a movement does not suit your gym or your body, I swap it for one that trains the same muscles.

Is there a free trial, and how does it work?

Yes. The yearly plan starts with 14 days free and the monthly plan with 3 days, both with no payment upfront. You build your plan and train before you decide anything. If it is not for you, cancel before your trial ends and you pay nothing at all.

How much does Charles cost?

After the free trial it is $19.99 a month or $119.99 a year. For comparison, a coach who writes and adjusts your programme by hand charges $150 to $300 a month for the same work. You subscribe through the App Store or Google Play and can cancel there in a few taps.
