Intense Cardio & Heart Risks? Study Spills All

Turns out, years of hardcore cycling or triathlons might leave more than just bragging rights—nearly half of older male endurance athletes in a new study had heart scarring! That scarring made them over 4.5x more likely to have dangerous heart rhythms. One cyclist’s fitness tracker even caught his heart racing at 238 bpm—he ended up needing a defibrillator implant. Experts say don’t ditch your workouts, but if you feel dizzy or weird, get checked. Wild, right? #Health #BodyHealth #HeartHealth
