Did you know your transverse abdominis acts like a natural corset for your spine? That's why maintaining a flat back is key in mountain climbers. Keep your core engaged and drive your knees toward your chest in a rhythmic motion to fire up your rectus abdominis, obliques, and glutes. 🔥 Save this for your next core workout. #mountainclimbers #coreworkout #hiitexercise #abtraining #bodyweightstrength #homefitness #gluteactivation #fatburning #wellnessjourney #healthyliving #getmoving

Crunches are a waste of time for a defined core. Instead, try this dynamic move. From a high plank, engage your abdominals and keep your back flat. Rapidly drive your knees towards your chest in an explosive, alternating motion. This targets your entire core, including deep stabilizers. 🔥 Send this to a friend who's still doing 100s of crunches. . . . #fitness #coreworkout #mountainclimbers #abworkout #hiitworkout #corestability #plankvariation #fatburningworkout
