Most people work out their core in pursuit of a flatter stomach, but the benefits extend way beyond aesthetics, improving both balance and posture.

A 25-year-old fitness enthusiast has demonstrated that a remarkable physical transformation can be achieved in just eight weeks through targeted exercise.

Leana, who goes by @fitzyelifts on TikTok, has garnered a substantial online following since sharing the training methods that helped her develop visible abdominal muscles.

In a recent clip, she revealed that kneeling skiErg workouts played a crucial role in her achieving a six-pack within two months.

Her documented journey has resonated with thousands seeking effective core-strengthening techniques.

The kneeling skiErg exercise requires positioning oneself on the knees in front of the machine, focusing on arm and torso movements that replicate skiing motions while maintaining stability.

This variation engages the upper body and core intensively whilst minimising strain on the lower body.

It also proves particularly beneficial for those recovering from lower-body injuries or seeking concentrated upper-body training.

By removing the legs from the movement pattern, practitioners can direct maximum effort towards core engagement.

The modified position allows for sustained abdominal activation throughout each repetition, making it exceptionally effective for developing visible muscle definition in the midsection.

Leana has also shared specific nutritional guidance on her website, emphasising the importance of selecting appropriate protein sources for optimal results.

Her recommended foods include cottage cheese, firm or extra firm tofu, egg whites, and other lean protein options.

She explained: "These protein sources are not only rich in essential amino acids but also contain minimal fats and carbs, making them ideal for building muscle while keeping a lean physique."

She clarified that this approach doesn't demonise carbohydrates or fats, stating: "This doesn't mean that carbs and fats are bad; it simply means that the protein is more concentrated, allowing you to manage your intake of carbs and fats separately for a more balanced and effective diet."

The combination of the kneeling skiErg exercise and strategic protein consumption enabled Leana to achieve her six-pack in just two months.

It demonstrates that targeted core training, particularly exercises that accommodate physical limitations, can yield rapid results when paired with proper nutrition.

Leana's transformation follows other impressive weight loss journeys documented by fitness enthusiasts online.

One social media revealed that a simple workout toned up her arms in just six weeks, following years of failed attempts.

Another gym-goer who transformed her physique also shared her approach to arm training on TikTok.
