When he was standing with his chest on the floor and only wearing a pair of black razors, it took Sam Walker-Goldsmith two weeks to decide whether or not he would upload a picture of himself.
In the first image, the 22-year-old retail manager weighs 160 kg. He is at his greatest, with "no confidence" and "no desire to achieve anything".
The second image is six months later and more than 50 kg lighter. It is a transformation that the man from Birkdale in Queensland required to revise his life, diet and exercise – but not to opt for surgery.
"I have a lot based on how I felt about my appearance," Sam said. "So I decided to do something about it."
Joining fitness program F45, Sam said the first two weeks of his training were the toughest.
"To say that this class was not one of the hardest things I've ever physically done would be a lie," he said.
"The class made me vomit three times and I never wanted to go back, so I finally went back and really thought about what I wanted to achieve during my fitness trip.
"In the first two weeks that I just trained while eating at least … I lost 10 kg."
Sam, who is now documenting his ongoing transition on Instagram, decided to start his transformation by doing an eight-week body challenge that required him to follow a fixed eating plan and train at least four or five times a week for 45 minutes.
"I accepted the challenge and thought that the most difficult part would be the training," he said.
"Oh boy, I was in a state of shock, changing your lifestyle is not as easy as I thought, and sticking to a clean and healthy meal plan for two months after I was out of fast food was probably one of the toughest mental decisions I've taken "I once made.
"Here I quickly realized that losing weight for me is not only a physical experience, but also one
mental battle daily to achieve your goals.
He said it took a month to take up the challenge before a change in his mentality was made and the shift in his weight began to happen.
"I started with double sessions (every 45 minutes)," Sam said. "I would do seven to twelve sessions a week, and by week eight I did 15 sessions within a six-day period."
The challenge, which gives the participants a meal plan to follow each week to remove water retention, eliminate the desire for sugar and build muscle mass, usually expects a minimum of five days for training sessions, which last 45 minutes.
The trainings focus on functional training and include exercises such as rowing, deadlifts, planks, squats and pushing weights.
According to Sam, at the end of the first eight weeks, he had lost a dizzying 21 kg before he jumped on board and took on a second body problem.
"These eight weeks were definitely a lot easier than the first, I loved the food, the food I hated as green beans, etc. I enjoyed the training I loved, and I skipped sessions," he said.
"For the eight weeks I was on average 16 sessions a week, I felt absolutely every week on Sunday.
"At the end of the second challenge I lost another 18 kg, which brings us now, I am currently at 109 kg of 160 kg.
"I stand in the mirror and remember what I looked like on a daily basis, and get frustrated and disappointed in how I got myself so big."
DAY ON A PLATE
According to Sams trainers, a typical day on a board can be during a challenge:
Breakfast: super green juice with boiled eggs or protein smoothie or chili tomato scrambled eggs
Morning tea: handful of nuts or protein shake or chocolate bliss ball
Lunch: chicken and goat's cheese zucchini salad or broccoli and cauliflower pilaf with chicken strips or Chinese pork and paksoi stir-fry
Afternoon tea: shake protein almonds or celery with tzatziki or an orange and 12 almonds
Supper: vegie puree with grilled fish or ptop steak with spinach and avocado salad or pesto chicken with roasted vegetables
Although he is satisfied with his progress, Sam says he has still not reached his goal weight loss goal.
"My frustration about what I looked like is driving my ambition and desire even more to achieve more, be faster, stronger, fitter and slimmer," he said.
"In the last six months I have had some doubts and days where things were not going according to plan, but from where I am today, there is still a long way to go before I look in the mirror and be satisfied, but I look forward to that day.
"[That goal] gives me every day motivation to wake up and get it. "
