Why Our Training Works: The Science Behind Strength, Structure and Consistency

At DH Training Club, our programming isn’t random. There’s a clear structure behind why you see certain movements repeated across the week, why rep ranges change, and why consistency always gets pushed over quick wins.

This blog breaks down the thinking behind it so you can understand exactly why you’re doing what you’re doing.

Muscles Are Always Either Growing or Shrinking

Your body is constantly adapting.

After a strength session, your muscles go through a process called adaptation:

They break down during training
Recover and rebuild stronger afterwards

But here’s the key point most people miss:

If you don’t train a muscle again within a certain window, that adaptation starts to drop off.

So effectively, your muscles are always in one of two states:

Growing (adapting to training)
Shrinking (losing that adaptation)

Why Twice Per Week Works

Training each muscle group twice across a 7-day period allows you to:

Re-stimulate the muscle before adaptation drops
Build momentum week to week
Improve both strength and muscle development more efficiently

Train it once, and you’re maintaining.Train it twice, and you’re progressing.

Why We Repeat Key Movements

It’s easy to think variety is the key to progress. In reality, targeted repetition is what drives results.

Muscles Work Through Specific Fibre Recruitment

Each exercise targets muscle fibres in slightly different ways:

Squat, more quad dominant, upright torso, knee flexion
Deadlift, more posterior chain, hamstrings and back
Hip thrust, glute focused, peak contraction at the top

Even though they all train the lower body, they:

Load muscles differently
Challenge different fibre ranges
Build strength in different positions

Alongside these lower body patterns, we also make sure there is consistent exposure to key upper body movements across the week:

Pulling patterns like pull ups or rows
Chest press variations
Shoulder press variations

This ensures full body development, balanced strength, and reduces the risk of imbalances over time.

Why Repeating Them Matters

By consistently performing these movements:

You improve technique
You recruit more muscle fibres over time
You can progress load safely and effectively

If exercises constantly change, you’re always starting from scratch.

At DHTC, we want you getting better at movements, not just doing more of them.

Why We Use Different Rep Ranges

You’ll often see these rep ranges across sessions. That’s not by accident.

The Goal: Stimulating Reps

Not all reps are equal.

The reps that actually drive progress are called stimulating reps. These are the reps where:

The weight feels challenging
You’re close to fatigue
The muscle is working hard enough to adapt

Why Moderate Loads Work Best

Using rep ranges like:

6–8
8–10
10–12

Allows us to:

Use moderate to heavy loads
Maintain good technique
Accumulate enough stimulating reps

This combination is where:

Strength improves
Muscle develops
Injury risk stays low

Too heavy all the time and technique breaks down.Too light and you’re not creating enough stimulus.

This is the middle ground where real progress happens.

PBs Matter… But Consistency Wins

Everyone loves a PB (personal best), and rightly so.

They’re a great sign that:

You’re getting stronger
Your training is working

But here’s the truth:

PBs are a result of consistency, not the goal itself.

If you:

Show up consistently
Repeat key movements
Work within the right rep ranges
Apply effort week after week

Then PBs take care of themselves.

Chasing them every session often leads to:

Poor technique
Plateaus
Frustration

The Bigger Picture

Everything in your training is there for a reason:

Training muscle groups twice per week keeps you progressing
Repeating key lifts improves strength and movement quality
Structured rep ranges ensure you’re working hard enough
Consistency builds long-term results

It might feel simple on the surface, but that’s the point.

Simple, structured, repeatable training done consistently will always beat random, intense, inconsistent effort.
