Triathlon pour tous : Embrasser le sport au-delà de l'athlète professionnel

Wondering what body fat percentage to see abs? While standard advice says 10% for men and 18% for women, the real answer is much more complex. Discover why muscle mass and genetics matter just as much as your body fat percentage, and learn how to build visible abs without chasing unrealistic numbers.

Wondering how many calories to gain a pound? While the classic 3,500-calorie rule provides a baseline, human biology isn't just simple math. Discover the real difference between gaining fat versus muscle, learn how to calculate the perfect calorie surplus, and find out why tracking your body composition is the key to healthy weight gain.

Wondering how long does it take to build muscle mass? While your strength will improve in just a few short weeks, visible muscle growth typically takes 6 to 12 weeks of consistent training. Discover the realistic muscle growth timeline, learn why the traditional scale can be misleading when you are building muscle and losing fat, and find out how tracking your body composition helps you measure your true progress.
