Your cardio is burning fewer calories now than when you first started.

Sounds like a L, but it’s actually the whole point of working out.

Your body is literally just adapting and becoming more efficient at the movement.

The problem is when you rely only on cardio to stay in a calorie deficit. Cardio is amazing for you—it helps you live longer, levels up your heart health, and boosts your energy and recovery. It’s the perfect add-on to a weightlifting routine.

But using cardio as your only tool for fat loss? Not it.

The drop-off in calorie burn over time isn't as extreme as some videos claim, but it's definitely enough to stall your progress if you aren't lifting or watching your diet.
