James Flex Lewis

Professional Bodybuilder

James “Flex” Lewis is a Welsh bodybuilder who’s won five Mr. Olympia 212 titles. He’s widely recognized for possessing the world’s best 212 physique.

James began his bodybuilding journey as a 12-year old; training at home with a simple set of weights made out of plastic. From there, he transitioned into sports, particularly rugby. Where he earned the nickname “Flex,” due to his flexibility, and the ability to avoid tackles.

He started training in the gym at the age of 15, to gain more size, and strength required to excel at Rugby. However, the process of gaining muscle mass “captivated” the youngster so much he decided to quit Rugby, and instead, dedicate himself to bodybuilding.

Since then, James has turned into a true bodybuilding star. He’s won over 28 contests since he first stepped on stage – becoming one of the greatest bodybuilders from the UK.

This is his story:

Training with Plastic Weights

James “Flex” Lewis began his bodybuilding journey at the age of 12, after he discovered a book full of pictures of Tom Platz. James was so impressed by Tom’s physique, especially his legs, that he said he wanted to look the same one day.

Another inspiration for James to start training was Arnold Schwarzenegger, one of the most iconic bodybuilders of his time.

James had a modest start to his bodybuilding journey – he would train using plastic weights at home at night, when his parents were asleep. Although his parents prohibited him from using the weights. James was so “enthralled” with them, that he continued to train regardless of his parents’ warnings.

A New Environment

At the age of 15, James began training more seriously; stepping into a gym for the first time in his life. The weights and machines he saw in the gym were much more complex than the basic weight set he trained with at home. So it took a couple of months before he adapted to his new training environment.

James initially started training to improve his performance in Rugby. However, after he saw the results from weightlifting, bodybuilding became his main priority in life.

Taking Advantage of his Potential

One day, while he trained at a gym, James met a local bodybuilder called Steve Naylor. Steve told James he had the potential to succeed in the sport of bodybuilding; suggesting he should compete on stage.

James took the advice he got from Steve, and began preparing for his first bodybuilding contest. They both trained together for a year, before James entered his first show – the Junior Mr. Wales. He won both his weight class, and the overall category on that day.

James also met an IFBB Pro bodybuilder at the competition, called Neil Hill. Neil helped him prepare for his next competition, which was only four weeks away. Impressively, James was able to win his second competition in a row – this time the 2003 EFBB Jr. Mr. Britain.

For the next four years, James won every show he participated in – including the 2007 British Nationals. A victory which earned him the Pro Card. Because of these feats, James established himself as a “force of nature” in the UK bodybuilding scene.

Moving to the Bigger Stage

After making a name for himself in the UK, James decided to move to the USA in pursuit of even bigger challenges; such as Mr. Olympia, and Arnold Classic.

For the first time since he started competing, James didn’t place 1st in a show; finishing in 7th at the 2008 Tampa Pro. However, James wasn’t “fazed” by this. He continued to work hard in the gym, eventually getting back on his winning streak.

He began taking home titles such as the 2009 IFBB Atlantic City Pro 202 Division, 2012 EVL’s Prague Pro 212 Bodybuilding, and the 2012 Mr. Olympia 212 Champion.

Pinnacle of Bodybuilding

By 2016, James had collected a sensational 28 bodybuilding titles. Including five Mr. Olympia 212 titles.

As a result of such “domination” on the Olympia stage, James is widely regarded as one of the greatest “212 bodybuilders.”

Flex has a strict training program, which is designed by his trainer Neil Hill. The program includes cycling repetition ranges, weight, training frequency, and other factors that are important for muscle stimulation. As James “Flex” says; “Never let your body adapt.”

In the off-season, he trains 6 days per week. His workouts last anywhere between 1.5 to 3 hours.

James’ Top 10 Training Tips

  1. Change Style – James always changes his workout routine to keep his muscles growing at a constant rate.
  2. Neglect, Subject, Perfect – This principle means focusing more on the weak body parts than the strong ones.
  3. Rethink Hardcore – James doesn’t follow traditional training rules. Instead, he creates his own rules; doing what yields the best results for his physique.
  4. Giant Strides –  Not super sets, not tri-sets, but giant sets. These are five-exercise sets which James does on a regular basis. His typical triceps giant-set consists of these exercises; EZ-bar push-downs, overhead rope triceps extensions, wide-grip rope push-downs, one-hand push-downs, and narrow-grip rope push-downs.
  5. Take the Highway – James prefers high reps, over low reps. He would rather do 15-20 reps with lighter weight, than 3 reps with a heavy weight.
  6. Be Unique –  The Welsh bodybuilder advises always creating new training techniques, and exercises. As he says; “Being innovative in the gym is the key to growing long-term.”
  7. Pushers –  According to James, having a training partner always helps. Especially in situations where he needs “extra push” for those last few reps.
  8. Turn up the Heat – In this principle, James advises training with an extreme intensity. He’s found the best way to do this is to incorporate at least one HIT workout each week; slowly progressing to more HIT workouts done in a week, over time.
  9. M-2-M – James says that beginner’s’ number one priority should be learning how to achieve the best possible “mind-muscle connection.”
  10. In the End – “Neglect nothing.” James pays attention to detail, even to the smallest muscles or exercises. He says that it’s those small details that separate champions from the rest.

To build his 5-time Olympia winning physique, James had to dedicate a lot of his time to diet; cooking, preparing, and eating six meals per day.

He eats clean all year round, even in the off-season. Some of the foods that can be found in his kitchen are green vegetables, lean meats, eggs, nuts, healthy butter, and avocados. For carbs, he consumes complex sources such as oats, brown rice, and sweet potatoes. These provide James with constant energy supply, needed for his intense workouts.

Idols and Influences

James’ early idols in bodybuilding were Arnold Schwarzenegger and Tom Platz. He admired their physiques; wanting to sculpt a similar build for himself one day.

While these two legends were his main inspirations in bodybuilding, James also found other influences during his bodybuilding journey.

Possibly the biggest influence was his long-time trainer Neil “Yoda” Hill, who helped him sculpt an immaculate physique. One that eventually won him the 5 Mr. Olympia 212 titles.

“For anyone who wants this to happen tomorrow you’re in the wrong sport. This is a marathon, not a sprint. Have patience young Jedi or you will ruin your Physique.”

Be it an amateur local contest, or the extremely competitive Mr. Olympia, James would always have his sights set on 1st.

Because of this mindset, he got to where he is today – at the pinnacle of his bodybuilding career, recognized by many as one of the best in his category.
