The 3 Training Principles That Get My Clients Strong in Just 30 Minutes a Week

October 02, 20251 min read

Most workouts you see online are way too complicated: split routines, six days a week, endless sets and reps. No wonder people burn out or never start.

The reality: you don’t need a fancy plan. You just need a few proven principles done consistently. These are the same principles I teach every single client — the reason my people get results in just 2x 30-minute sessions a week.


Principle 1: Focus on the Big Lifts

Squats. Presses. Deadlifts. Rows.

These are your “money moves.” They train the most muscle in the least amount of time.

And no — that doesn’t mean everyone has to barbell back squat. If that doesn’t feel good, we swap for trap bar deadlifts, dumbbell goblet squats, or leg press. There’s always a way to train smart without beating up your body.


Principle 2: Full-Body Workouts Win

Forget the idea that you need a separate “arm day” or “leg day.” Full-body training is more efficient, more practical, and just as effective — especially for busy people. Pair that with smart rest and recovery, and you’ll make progress without living in the gym.


Principle 3: Train Hard Enough

This one is big. Most people stop too soon. Your muscles grow and your body changes when you push close to failure. That doesn’t mean sloppy form — it means learning to recognize when you’ve got 1-2 good reps left in the tank.

That’s where the magic happens.


Wrap-Up

These are the foundation. In future posts I’ll dive deeper into form, recovery, nutrition, and mindset — because real strength is built inside and out. .
