Caffeine and Training: What You Should Know

Is your daily coffee helping or hurting your training? Let’s find out.

Caffeine is one of the most effective (and totally legal!) performance boosters available. It can help increase energy, focus, and endurance — which is why so many people use it before a workout. But to get the benefits without hurting your recovery, it helps to use it smartly.


Why Caffeine Helps

Caffeine acts on your central nervous system to:

  • Increase alertness and reaction time

  • Make exercise feel a bit easier (you feel like you can push more)

  • Improve endurance and power output

So yes — that pre-training coffee isn’t just psychological. It actually works.


How Much Should You Take Pre Training?

A good starting point is 2-3 mg per kg of bodyweight but this can be increased to up to 6 mg.  There is around 60-100mg in a coffee and your average energy drink contains around 160mg - 200mg Caffeine.  

Start on the lower end and only increase if needed.


Timing 

Take caffeine 30–60 minutes before training.

But be careful: Caffeine can stay in your system for up to 8 hours so if you train in the evening, it may disrupt your sleep.

Good rule: Avoid caffeine after 2PM as poor sleep = weaker recovery + slower progress.


Keep Your Tolerance in Check

If you rely on caffeine all day every day, your body becomes less responsive.

Try:

  • Saving caffeine for when you train or when you really need focus.

  • Having some caffeine-free hours or days each week.

This helps you keep that “buzz” without increasing how much you need.


Quick Takeaways

  • ☕ 1–2 coffees pre workout seems to work for most people.

  • ⏱️ Take it 30–60 minutes pre-workout.

  • 😴 Avoid caffeine later in the day to protect sleep.

  • 🎯 Use caffeine with purpose (not constantly).

  • 💧 Hydrate — your muscles still need water to perform well.


Bottom Line

Caffeine can be a fantastic training tool when used intentionally.
It can boost performance, motivation, and energy — but sleep and recovery always come first. If caffeine starts affecting your sleep, dial it back.

Use it wisely, and let it support your training, not replace good habits.

Do You Really Need Supplements?

Walk into any health shop and you’ll see shelves full of powders, pills, and potions promising big results. But do you  really  need supplements to get fitter, stronger, or healthier? The truth:  no — not if your diet is already balanced.  Supplements are exactly that — a way to  supplement  your nutrition, not replace it. ⚖️ The Pros & Cons of Supplements Pros: Convenient when whole foods aren’t enough Can help fill gaps in your diet Backed by research in some cases (like creatine and vitamin D) Cons: They’re not magic — you still need to eat well and train consistently Can be expensive if you’re taking things you don’t really need Not all supplements are created equal (quality matters!) ✅ The Supplements I Recommend There are just a few that I suggest most people take: Vitamin D3 (4000iu daily):  Especially in the UK where we don’t get much sunlight. Supports bones, immunity, and overall wellbeing. Creatine (5–10g daily):  One of the most re...

When’s the Best Time to Eat? (How to time meals around training)

Meal timing can make a big difference to your  energy, performance, and recovery  — but it doesn’t have to be complicated. You don’t need to track every bite or plan your day around food. What really matters is  creating simple, consistent habits  that support your training and lifestyle. Here’s how to get it right 👇 🍳 Start Your Day Right Breakfast really does set the tone for your day — especially when it’s  high in protein . A balanced breakfast helps: ✅ Stabilise your energy levels. ✅ Keep you full for longer. ✅ Reduce cravings and snacking later on. Example: Scrambled eggs on wholegrain toast with avocado, or Greek yoghurt with berries and oats. If mornings are hectic, a  protein shake and a banana  are still better than nothing — you’re giving your body fuel to perform. 🏋️‍♂️ Fuel Around Training If you’re training hard (like we do at CrossFit Greater Brislington),  when you eat around your workouts  can make a big difference to how ...

How Often Should You Train?

 This is one of the most common questions we get asked — and honestly, it’s a good one. Some people think they need to train every day to see results. Others worry that if they can only make it two or three times a week, it’s not enough. The truth?  It depends on your goals, your recovery, and your lifestyle. 💪 For General Strength & All-Round Fitness If your goal is to move better, get stronger, and improve your fitness —  training 2–4 times per week  is more than enough when you follow a structured program (like ours). Why? Because progress comes from a balance of  training hard, recovering well, and staying consistent. Even elite athletes build rest days into their week. The magic doesn’t just happen in the gym — it happens when your body adapts between sessions. 🧠 It’s About Quality, Not Quantity Doing 2–4 well-planned, purposeful workouts each week will give you far better results than seven half-hearted sessions with no plan. Each time you train, you...
