Improving cardio for MMA isn’t just about running laps—it's about training smart. Mix in high-intensity interval training (HIIT) to mimic fight pace, pushing through explosive bursts with short rests. Add roadwork with sprints, not just jogs, to build endurance and recovery speed. Jump rope for footwork and rhythm. Spar regularly—it’s the best real-time cardio. Don't skip strength training either; muscular endurance matters. And most importantly? Breathe. Controlled breathing under pressure keeps your tank full longer. Train your lungs like you train your fists—consistently and with intention.
