The Top Ten Barriers to Fat Loss (and How to Overcome Them)
Fat loss is often reduced to a simple equation of calories in versus calories out. While this principle is fundamentally correct, real world fat loss is shaped by physiology, behaviour, recovery, and environment. When progress stalls, it is rarely due to a lack of motivation. More often, it is the result of predictable biological and behavioural barriers.
Leptin and Ghrelin: Why Hunger Isn’t Just About Willpower
If managing your appetite feels harder than it “should” be, you’re not broken and you’re not lacking discipline. Hunger is controlled by powerful biological systems designed to keep you alive, not slim. Two of the most important players in this system are hormones called leptin and ghrelin.

The Benefits of Strength Training: for Every Body
How to start strength training the right way
If you’re new to lifting, start with the basics. Here are five simple movements that form the foundation of most programmes:
Squat - strengthens legs and glutes

Push-up - develops chest, shoulders and arms
Row - strengthens back and posture muscles
Plank - builds core stability and balance
Technique always comes first, then I gradually increase resistance, intensity and complexity.
How to Stay Fit Through Winter
Change your timing - If dark evenings put you off, try training first thing in the morning or during lunch breaks. Get it done before the day takes over.
Adjust your goals - Winter doesn’t have to be about smashing PBs. Focus on maintenance or small wins - consistency beats intensity right now.
Train indoors - If outdoor workouts are less appealing, swap for indoor sessions. Bodyweight circuits, resistance bands or gym-based PT sessions keep you warm and on track.
Layer up - For those who enjoy the outdoors, invest in good cold-weather gear. Once you’re moving, you’ll warm up fast.
Prioritise recovery - Winter can increase stiffness and fatigue. Stretch, sleep well and hydrate - your body will thank you.

"What If I Can't Do It?" - Overcoming the Fear of Trying New Exercise
How to Overcome the Fear of Starting Something New
You don’t have to wait for the fear to disappear. You just have to learn how to move forward with it.
Here’s how:
✅ Name the fear.
Be specific. Are you afraid of failure, looking silly, or getting injured? Naming it takes away its power.
✅ Flip the “what ifs.”
Instead of “What if I can’t do it?” try “What if this changes my life?”
What if you feel stronger, sleep better, reduce stress, and gain confidence?
✅ Take one small step.
Don’t aim for perfection. Aim for progress. One class. One walk. One session. The first step is the hardest - and the most powerful.
✅ Choose the right environment.
Supportive, judgment-free spaces like Griffin Fit are key. You don’t need a six-pack or perfect form. You just need to show up.
✅ Work with a coach who listens.
You’re not just a number. We take the time to understand your story, your needs, and your pace. Our job is to make your journey enjoyable, not stressful.
✅ Visualise success.
Close your eyes and imagine yourself six months from now: fitter, stronger, more confident. Let that image pull you forward.
