No Time to Train? How to Get Results in 3 Sessions a Week

By , BSc (Hons) Sport, Fitness & Coaching · · 7 min read

Let me guess: you have no time

If you're reading this between school runs, a work call and what's for dinner, this one is for you.


I get it. I'm a dad, I run two businesses and I'm about to launch a third. I coach Gaelic, and my son plays four sports. Between school runs, homework, dinners, bath time and getting out the door for training, there is not much day left. And I work in a gym. If I'm short on time, imagine adding a 15 to 30 minute drive each way on top of all that.


So when someone says "just train five days a week", I know exactly how it goes. It lasts a fortnight. Then one missed session becomes a missed week, and the plan quietly dies.


The problem isn't your motivation. The plan was never built for your life. This article covers how much training you actually need, how a 3 day week works, and the mistakes that waste the time you do have.

Why most training plans fail busy people

Most plans are written for people with spare time. That's the root of it. Here is where they break down:

  • Too many sessions. Five or six days a week looks great on paper and falls apart the first time work runs late or a child is sick.
  • All or nothing. Miss one session and the whole week feels written off, so people stop.
  • Hidden time costs. A 45 minute session is really 90 minutes once you add the drive, parking and getting changed.
  • Too much guesswork. When you only get a few hours, working out what to do on the day wastes the time you had.

None of that is a willpower problem. It's a design problem, and it can be fixed.

How much training do you actually need?

Less than you think. The UK Chief Medical Officers' guidelines, updated in July 2026, say adults should do muscle-strengthening activity on at least 2 days a week, alongside at least 150 minutes of moderate intensity activity.


The research on training frequency points the same way. A 2019 review by Grgic, Schoenfeld and Latella concluded that when the total amount of training is the same, how often you train does not seem to have a pronounced effect on muscle gain. A study by Lasevicius and colleagues compared training twice a week with three times a week over 10 weeks in resistance-trained men and found similar gains in strength and muscle size.


In plain English, what matters most is the quality and total amount of hard work you do and how consistently you do it. It matters much less whether that work is spread across three days or five. Most of that research is in men, but it makes the same point I see with clients: three well-planned sessions you actually do will beat five you keep missing.

How a 3 day training week works

The structure is simple. Three sessions a week, on non-consecutive days, so your body has time to recover and your week has room for everything else. Monday, Wednesday and Friday works well. So does Monday, Wednesday and Saturday if weekends are easier.


This is the split I use with busy clients:

  • Day 1, Upper body: pressing and pulling movements
  • Day 2, Lower body: squat and hinge patterns
  • Day 3, Full body: a bit of everything, so nothing gets left behind

Four things make it work:

  1. Big movements first. Squats, hinges, presses and rows give you the most for your time. Save the extras for the end, or skip them on a rough week.
  2. Progressive overload. To keep changing, you have to do a bit more over time, whether that's more weight, more reps or better control. You can only do that if you write it down, so use the free Training Log.
  3. Know the plan before you walk in. Planned sessions mean no standing around deciding what to do, so none of your limited time is wasted.
  4. Eat for the goal. Training only does half the job. The free calorie calculator takes about 10 seconds and gives you your calories and your protein target.

If fat loss is your main goal, my free Fat Loss Guide covers the nutrition side in more detail.

Five mistakes that waste a busy person's time

  1. Planning more than you can keep. Pick a number you can hit in your worst week, not your best one. Anything extra is a bonus.
  2. Making it up on the day. Winging it feels like training, but it's usually the same few exercises at the same weight.
  3. Not tracking. If you can't see what you lifted last time, you can't beat it, and progress stalls.
  4. Trying to out-train the food. Extra sessions won't fix guessing at your calories and protein. Sort the basics first.
  5. Waiting for a perfect week. There isn't one. Start with the week you have and adjust as you go.

Where to start

Start with the free tools. Use the calorie calculator to get your numbers, then open the Training Log so you can track every session.


If you want a plan for this week without committing to 12, start with the 7 Day Kickstart. It's £7 and gives you 3 introductory gym sessions with a video for every move, your calorie and protein targets and 12 example meal days. Finish it and you get £10 off Project 90.


When you're ready for the full plan, that's why I created Project 90 3 Day. It gives you the structure of Project 90 in a version built for a busy week, and it's based on what I've learned working with over 1,000 clients who were in the same position as you. Every session is planned, so all you have to do is turn up and follow it.


It's a one-off payment of £97. No subscriptions, no monthly fees and access for life. Results vary from person to person, but follow the plan and you give yourself the best chance.


If your main goal is glutes, take a look at The Glute Programme. If you want someone in your corner, apply for one-to-one coaching, in person in Belfast or online.

Frequently asked questions

How many days a week should I train?

The UK guidelines say at least 2 days of muscle-strengthening activity. Three days gives you a bit more room to progress while still fitting around work and family, which is why I use it with busy clients.


Can you build muscle training 3 days a week?

Yes. When the total amount of training is the same, research suggests how many days you spread it over makes little difference to muscle gain. Three consistent, planned sessions a week is plenty to build muscle and strength.


Is 3 days enough to lose fat?

Fat loss mainly comes from eating fewer calories than you use. Training three times a week helps you keep and build muscle while you do it. Use the free calorie calculator to get your starting numbers.


What if I miss a session?

Do the next one. Don't try to double up and don't write the week off. One missed session changes nothing. Quitting changes everything.
