On Your Marks GET SET


Trans formations

“I have dropped 1kg this week - so hopefully in a few weeks I will be down to my target weight. At this point I would be happy to maintain that weight and focus on building muscle“
“Alex is doing more for me than I could imagine. The fact that food is a friend right now is the biggest step forward and the fact I've lost weight on the food plan he gave me with carbs has flabbergasted me!“
“Working with Alex has seen me lose 6lbs in 1 week! I've never lost that much in a week ever. I've eaten everything he wrote in my plan and was surprised by how full I was. Also, sorry for the detail but I've also been on my menstrual cycle this week so that's literally crazy!“
"As a new mum, Alex is the absolute best to work with. He combined exercises to build up my strength and confidence from the core out, with a nutrition plan that adapted for breastfeeding and was mindful that, some days, you need to cheat when you haven’t slept.   I built mental and physical strength and stamina that got me ready for birth and and being a mum. I used the lessons and the programme for my second child, with some online check- in despite having moved away - so amazing value for money! Alex is also a really great babysitter so sessions were super fun too!"

Achieving your goals

My 3 pillars of success


If you are not motivated, then you will not succeed at anything. Motivation is paramount to success. I am there for you during the highs and also when things seem tough. Like a big annoying brother someone you can trust and who’s got your back!…


If you want to feel more comfortable in your own skin, exercise will help! If you want to be in better shape, then you need to train. It can be that simple. I will use my extensive experience to create the training plan that matches the wishes you have…


Gone are the days where you need to restrict the food you eat to achieve the results you want. If you consume more calories than you burn, you gain weight. If you burn more calories than you consume, you will lose weight. Simple as that. I make individual diet plans that match your desires and goals…

Coaching philosophy

My approach to coaching

My philosophy is simple. When you’re looking to make a change exercise faith, patience and positivity. My personal mission has been to help people ‘lift weights and their spirits’. In a world that is as fast as it is slowing down, being ‘selfish’ and concentrating on yourself is the best investment you can make. One that will positively impact all areas of your life. I want to help you wear a smile on your face every day, not have to question what you should be eating (while educating you along the way) and be there to celebrate your wins when you accomplish them, and you will accomplish them. What waits for you is ultra-convenient personalised PT I am here to help you every step of the way.
