New viral fitness trend the #75HARD challenge promises to transform your life in 10 weeks

A new viral fitness trend which promises to transform your mind, body and life in 10 weeks has taken the internet by storm.

Created by American entrepreneur and podcast host Andy Frisella, the #75HARD Challenge is described as a ‘mental toughness test’ which pushes the limits of the human condition through 75 days of rigid diet and rigorous exercise.

Interior designer and ‘micro’ fitness influencer April, 31, from Melbourne, is currently on Day 25 of the challenge, which she admitted has already tested her both physically and mentally.

Followers of the #75HARD movement must adhere to five fundamental rules for the duration of the programme.

These include exercising twice a day for a minimum of 45 minutes per session, with one workout conducted outdoors.

A strict diet must be followed for the full ten weeks, with no cheat days allowed.

#75HARD does not stipulate a specific meal plan, but no chocolate, cake, soft drinks or alcohol may be consumed.

Participants must also drink four litres of water per day. 

The #75HARD Challenge involves a strict diet with no chocolate, cake, soft drinks or alcohol allowed, and a rigorous exercise regimen of two 45 minute workouts each day – one of which must take place outdoors

To stimulate the mind, followers must read a minimum of 10 pages of a self-help or personal growth book each day.

Fictional literature is not allowed.

Progress photos must also be taken every day throughout the challenge to highlight the dramatic physical change at the end of the 75 days.

All this may sound difficult, albeit possible, but the major caveat of the #75HARD Challenge is that it must be followed for 75 consecutive days – stumble on day 74 and you must start all over again.

The #75HARD hashtag is already linked to more than 76,000 Instagram posts, many of which show incredible transformations like this incredible 55 pound weight loss

Mother-of-three April said while the challenge has taken up all of her extra time, she’s already feeling the benefit on Day 25.

‘It has certainly been testing me – mentally and physically!’ she wrote in an Instagram post.

‘Regardless, I’ve been sticking it out and I’m pretty amazed at the lessons I’ve learnt so far – things about myself and the habits I need to improve on.

‘It’s been incredibly eye-opening so far!’

And it seems she’s not alone.

The #75HARD hashtag is already linked to a staggering 76,016 posts on Instagram, many of which show incredible physical transformations less than half way through the programme.

One woman credited #75HARD for resolving her unhealthy relationship with food, by training the mind to believe it is stronger than its desire to make poor choices.

Proving he practices what he preaches, founder Andy Frisella has experienced years of personal growth by following the challenge himself.

He shares regular progress updates with his 1.5 million followers on Instagram.
