The Late Apex PT

My name is Iain Harper
(The Late Apex PT)


I’m a personal trainer, online coach, vegan nutritionist, and mental health first aider who specialises in functional strength and fitness powered by whole food plant-based nutrition.


I’ve helped many people in their 40s and 50s return to (and surpass) the kind of shape and levels of strength and fitness they remember enjoying back in the day.


I’m in my early 50s myself and completely empathise with how easy it can be to let other things in life take priority. I also know from personal experience how rewarding it is to regain the freedom of rejuvenated health and wellbeing.

I’ve designed two very affordable versions of RetroFit, but before I explain what each one offers I’d like to invite you to subscribe to my mailing list.


As a subscriber you’ll receive an email from me around once a fortnight containing practical advice and guidance about how you can improve your functional strength and fitness and plant-based nutrition.


By way of thanks for subscribing, I’ll give you a 10% discount code to redeem against the price of a RetroFit plan, plus a PDF containing some of my whole food plant-based meal ideas for you to experiment with.


Just enter your email address and name below and then hit the subscribe button.


Keep scrolling to read all the details about the two versions of RetroFit (programme only or personalised coaching).


Once you’ve decided which one will suit you best, hit the orange ‘sign up’ button.


I use Stripe to process payments via debit and credit cards, Apple Pay, and Google Pay.

Client Testimonial:   “RetroFit was a brilliant way to get back to strength and fitness. It worked around my injuries, which improved so quickly with the programme. Iain is patient, and great at motivating in the way I needed and keeping me going when it got tough.”
