Every year, the fitness world rolls out a fresh batch of ‘must-do’ rules, miracle methods, and influencer-led routines that promise life-changing results.

Some are harmless.

Some are helpful.

And some… are best left in the past.

At AdMac Fitness, we’re big believers in training that fits real lives, delivers results, and doesn’t wreck your health in the process. So here are the fitness fads we’re happily leaving behind in 2026.

Waking Up at the Crack of Dawn

If you’re naturally an early riser — brilliant. Crack on.

But if you’re dragging yourself out of bed at 4:30 am because an influencer said it’s the only way to be disciplined, we’re not buying it.

Sleep is non-negotiable.

It’s when you recover, regulate hormones, build muscle, and support fat loss. Chronically cutting sleep just to squeeze in an early workout is counterproductive. You might get away with it for a short while, but eventually the cost of reduced sleep will outweigh the benefits of the early workouts.

A well-rested session beats a half-asleep dawn workout every time, and it’ll be a lot safer. When you’re tired, your technique and focus can suffer, which will impact your training significantly.

Rule of thumb:

Train when you can be consistent, energised, and focused — not when Instagram tells you to.

Starvation to Lose Weight

Let’s clear something up…

Here at AdMac Fitness we’re fans of fasting. We are not fans of starvation.

Fasting is:

  • Planned

  • Time-limited

  • Used strategically to improve insulin sensitivity, appetite control, and metabolic health

Starvation is:

  • Chronic under-eating

  • Driven by fear of food

  • A fast track to fatigue, hormone issues, muscle loss, and stalled progress

If you’re constantly exhausted, cold, irritable, and plateaued — that’s not ‘discipline’. That’s under-fueling. When you adopt this approach, you risk losing a lot of muscle, strength and injury resistance. These things are all hard to regain, so think carefully about your approach to fat loss.

Fat loss should support your health, not sabotage it.

Super-Long Workouts

If you’re resistance training for general health and fitness, but you're working out for two hours at a time, we’re willing to bet one of two things is happening:

  1. You’re resting far too long between sets

  2. You’re not training hard enough

Effective training is about quality, not duration. The goal is to stimulate muscle tissue across various movement patterns, joint ranges and resistance levels at an appropriate intensity. When you repeat this 3-4 times per week over a significant period of time, you’ll see huge benefits.

A focused 45-minute session:

  • With intent

  • Progressive loading

  • Minimal distraction

…will outperform a sluggish two-hour gym wander every day of the week. So this is your cue to get off your phone, get your head into the workout and enjoy the benefits of a focused session. Plus, you’ll have a lot more spare time for other activities as well!

Remember… Train hard. Train smart. Get out.

Traditional Body Part Splits (For Most People)

This one might ruffle a few feathers — but hear us out.

Unless you’re:

  • A competitive bodybuilder

  • With years of training behind you

  • And a very specific goal

You’re probably better off not training one body part per week. The research has shown this time and again over the years. More frequent stimulation of muscle tissue builds bigger muscles more quickly, reduces injury risk and helps to prevent muscle imbalances.

Full-body training or larger splits like push / pull / legs:

  • Stimulate muscles more frequently

  • Improve strength faster

  • Burn more calories overall

  • Fit real schedules far better

Training chest once every seven days isn’t optimal for most busy adults trying to get fitter, stronger, and leaner.

The theory with a traditional body part split is that you train one body part really hard, then it takes a week to recover before you train it again. The problem is, it simply doesn’t work like that. Tissue doesn’t need a whole week to recover, so it starts to catabolise before you train again.

Taking Thousands of Supplements

Supplements can be useful. - very useful in fact. They can also be massively overdone.

You don’t need a cupboard full of powders, pills, and potions to make progress. with your health and fitness. In fact, there’s a good chance that what you’re actually doing is wasting a lot of money.

For most people, this covers the bases:

Anything beyond that should be purposeful, not panic-driven.

If you’re eating well, training properly, and sleeping enough, supplements should support the process — not replace it.

What We’re Actually Backing in 2026

So we’ve been through what we don’t believe in, and won’t be falling for, but what are we actually in support of? Here’s a list of what we like…

✔ Sustainable routines
