The "Minimum Effective Dose" Workout for Busy Dads To Get Jacked and Strong
What if everything you believed about getting in shape was wrong?
What if training 6 days a week was actually holding you back? What if those HIIT classes were destroying your joints? What if the reason you can’t stay consistent isn’t discipline, it’s that you’ve been following the wrong plan?
Let me paint a picture.
It’s 6pm. You just got home from work. Your lower back is stiff from sitting all day. The kids need dinner. Your wife needs help. And somewhere in the back of your mind, you’re thinking “I should really get to the gym.”
But you’re exhausted. And the thought of doing some Instagram influencer’s 90-minute “ultimate shred” program makes you want to lie down.
So you skip it. Again.
The fitness industry has been lying to you. They’ve convinced you that getting in shape requires suffering. That you need to train 5-6 days a week. That you need to “earn” your results through pain.
It’s all nonsense. And it’s keeping you stuck.
I used to believe the hype too. More is better. No pain, no gain. Push through the fatigue.
It got me injured. Beat up. Burnt out. And eventually, on a surgeon’s table.
Now I know better. The dads who actually stay lean and strong year after year? They’ve figured out something different. Something called the Minimum Effective Dose, the smallest amount of training that produces the biggest results. Maximum muscle. Minimum fatigue. Minimum time. Minimum joint destruction.
That’s what I’m going to share with you today.
Why Everything You’ve Been Told About Training Is Wrecking Your Body
Here’s the trap most dads fall into:
You either go way too hard (CrossFit, HIIT classes, chasing PRs every session like you’re 22 again) or you go way too easy, walking on the treadmill for 20 minutes and calling it a workout.
Both approaches fail. And I’ve made both mistakes myself.
When I was younger, I was obsessed with maxing out. Every week, 52 weeks a year, I’d load up the bar and go for a new PR. Shoulder tweaky? Rub some horse liniment on it until it burns. Feeling tired? Hit the smelling salts. It didn’t matter how I felt. I was going in and pushing.
The result? I was beat up constantly. Nagging injuries. Joint pain. And eventually, a trip to the surgeon’s office.
Here’s the question I wish I’d asked myself back then: “What is the biological cost of your training?”
Most programs, especially the trendy ones, destroy your joints, tank your immune system, wreck your sleep, and leave you more fatigued than when you started. Short rest periods, high reps, technical lifts done under cardiovascular debt... it’s an injury factory.
CrossFit, Orange Theory, most HIIT classes: they’re the opposite of what I’d recommend for a guy over 35. You’re doing Olympic lifts while breathing heavy. You’re racing against the clock on exercises that require technical precision. You’re taking zero rest between sets.
And then you wonder why your shoulder is clicking and your knees ache.
Here’s what actually works:
You don’t need hours of cardio or 6 day a week programmes. Myself and my clients get in fantastic shape walking as much as we can. Doing sprints/airbike intervals once/twice a week. And lifting heavy in the 6-12 rep range with long rest periods, 2 to 3 minutes between sets.
No circuits. No metcons. No “fat loss training.” Just heavy compound lifts, taken close to failure, with enough rest to actually recover.
That’s the Minimum Effective Dose. And it works because it respects one simple truth: the goal of training isn’t to crush yourself. It’s to build yourself up, stronger, leaner, more resilient, without breaking down.
You should feel better after every session. Not wrecked.
The protocol is built on four principles:
Lift in the 5-10 rep range (occasionally up to 12)
Rest long enough to actually recover between sets
Choose exercises that fit YOUR body, not someone else’s
Minimize fatigue so you can show up consistently
Imagine training 3 days a week, never dreading the gym, watching your strength climb month after month, while your mates are icing their knees and complaining about their shoulders.
That’s the goal. Let me show you how to get there.

The 5-Step Minimum Effective Dose Protocol for Busy Dads
Here’s a quote I come back to constantly: “The first form of progressive overload is better technique.”
Before you add weight to the bar, master the movement. Your tendons and ligaments don’t adapt as fast as your ego wants them to. Slow down. Get better at the basics. The strength will come.
Now, here’s the protocol:
1. Train 3 Days Per Week (And Actually Recover)
Mot of the guys I work with, I often have them training just 3 days a week. Why? Because they need to be fresh when it matters. They can’t afford to be fatigued and broken down all the time.
You’re the same. You need to be fresh for your kids, your job, your life. You can’t afford to be dragging yourself through the week because you “crushed legs” on Monday.
More recovery means more muscle growth, less joint pain, and more energy for everything outside the gym. Three solid sessions per week, with real rest days in between, will outperform six mediocre sessions where you’re running on fumes.
An upper/lower/full body split works brilliantly here. You can do upper and lower back-to-back early in the week, then fit the full body session in whenever life allows. Flexible, effective, sustainable.
This is the current protocol the guys are following in the Jacked Dad Club.
2. Stick to the 5-10 Rep Range (Ditch the High-Rep Burnout)
Here’s something the science has finally caught up to: lower reps are less fatiguing than higher reps.
We used to think the opposite. We thought heavy sets of 3-5 reps fried your nervous system. Turns out, it’s the high-rep sets (15, 20, 25 reps) that cause more central fatigue and leave you feeling drained.
The legends knew this decades ago. Vince Gironda, the “Iron Guru,” said he never recommended more than 6-8 reps for hard gainers. Larry Scott, the first Mr. Olympia, built his physique on sets of 6-8.
For most exercises, most of the time, stay in the 5-10 rep range. You’ll build strength, build muscle, and finish your workouts feeling strong, not destroyed.
Save the higher rep stuff (12-15) for isolation work or machines where it makes sense. But your big compound lifts? Keep them heavy-ish and controlled.
3. Rest 2-3 Minutes Between Sets (Yes, Really)
I know what you’re thinking. “Two to three minutes? That feels like I’m being lazy.”
You’re not.
Shorter rest periods cause more fatigue. They’re also worse for muscle growth. When you rush between sets, you can’t lift as heavy, your form breaks down, and you accumulate more stress with less stimulus.
Sprinters rest 5 minutes between sprints. They’re not doing circuits. They’re building explosive power with full recovery.
You’re not doing a circuit either. You’re building strength. Take the rest. Scroll your phone. Catch your breath. Then hit the next set fresh and strong.
This is especially important for compound lifts: squats, deadlifts, presses, rows. These movements are demanding. Give your body time to recover between sets, and you’ll lift heavier, with better form, and get more out of every rep.
4. Choose Exercises That Fit YOUR Body (Not Someone Else’s)
This one took me years to figure out.
There are no exercises you “have to” do. None. Not barbell back squats. Not conventional deadlifts. Not flat bench press.
Everyone should squat, hinge, push, pull, lunge, and carry. Those are the movement patterns. But the exercises you use to train those patterns? Those should fit your body, your structure, your injury history.
Maybe barbell squats feel awful on your knees, but hack squats feel great. Use hack squats.
Maybe conventional deadlifts wreck your lower back, but trap bar deadlifts feel smooth. Use the trap bar.
Maybe flat bench aggravates your shoulders, but dumbbell presses or a good machine press feel fine. Use those.
The best exercise for me might not be the best exercise for you. Find what feels good, load it progressively, and stop forcing yourself into movements that hurt.
I used to say “rage against the machines,” that everyone should only use free weights. I was wrong. Machines are less fatiguing, safer to take to failure, and for certain people on certain exercises, they’re the best choice. Use whatever works.
5. Walk As Much As Possible (Your “Cardio” Is Handled)
You don’t need to suffer on the treadmill. You don’t need spin class. You don’t need to do burpees until you want to die.
For fat loss, your cardio can be as simple as walking as many steps a day as possible.
Walking burns calories, aids recovery, improves your mood, and puts zero stress on your joints. It’s the perfect complement to strength training.
Now, if you want to optimize for cardiovascular health and longevity, you’ll eventually want to add some Zone 2 cardio (where your heart rate is elevated but you can still hold a conversation) and some high-intensity intervals. But for getting lean? Walking is enough.
Track your steps. Aim for 10K. Take calls while walking. Walk after meals. Park further away. It adds up fast, and it works.
The Bottom Line
You don’t need to train like a 25-year-old to get in the best shape of your life. In fact, training like a 25-year-old is probably what’s been holding you back.
The Minimum Effective Dose approach is simple:
3 sessions per week, with real recovery between them
5-10 reps on your main lifts, with long rest periods
Exercises that fit your body, not someone else’s highlight reel
10K steps daily to handle your cardio without the suffering
Track your workouts. Track your weight. Film your lifts occasionally and watch them back. Hold yourself accountable, but also give yourself grace when life gets in the way.
You’re not going to be perfect. You’re going to skip sessions. You’re going to have weeks where the steps don’t happen and the diet goes sideways.
That’s fine. That’s life. That’s being a dad.
What matters is that you have a system that works when you show up. A system that builds you up instead of breaking you down. A system you can stick to for years, not weeks.
This is that system.
Now go lift something heavy. Then rest. Then do it again next week.
You’ve got this.
P.S. If you’re reading this and thinking “this sounds great, but I don’t want to build my own program,” I’ve got you.
