Team Optimum Nutrition UK 🤝🏼

Genuinely can’t believe I’m writing this

But I have teamed up with Optimum Nutrition 🤯

Anyone who knows me will know it’s been my choice of protein and creatine for YEARS

Ever since I’ve been training I’ve had an ON supplement on the go

When I started posting on this account 6 years ago

It’s been my dream to work with this brand

Alex Hormozi has this amazing quote which goes

‘Do so much work it’s unreasonable for you not to succeed’

I really felt that today

Use code ‘JACK’ at Optimum Nutrition for 15% off

Thank you

HALF IRONMAN DISTANCE BRICK SESSION 🚴🏃

Sat at the kitchen table this morning and watched the rain pour

Contemplated not going

Gave my head a wobble and did it anyway

I think this is the longest I’ve ever exercised in one sitting 😂

Now it’s time for a few rest days

Bike average heart rate - 144bpm

Run average heart rate - 153bpm

Alderford Olympic triathlon next weekend

3 weeks to Ironman Weymouth 70.3

It’s all coming together

SAVE THESE MUSCLE GROWTH WORKOUT SPLITS 💪🏽

25/08/2026

5 strength exercises every runner should be doing (& why!)

Barbell squat
Single leg leg extension
Bulgarian split squat
Sled push
Barbell calf raise

These exercises build strength in your quads, hips, hamstrings, glutes and calves

These are the foundation for better running performance

Iso-lateral (single leg) exercises are fantastic for working out muscle imbalances

Whether your goal is to run faster, stay injury-free or feel stronger on your runs

Give these a go

SAVE FOR LATER 💪🏽
