The next time you want a "new" core exercise give a loaded carries a try. You might be asking, what is a carry? Carries might be one of the most simple core movements to perform, pick up something heavy and walk. All the muscles of the core must fire to protect our spine from moving while carrying heavy things. Your body will always get it right, no thinking are my hips in the right place like while planking.
Types of carries;
Farmers walks: holding two objects (dumbbell, kettle bell), one on each side.
Suitcase walk: hold on object by the side.
Rack (position): hold object (1 or 2) up by shoulders.
Overhead: hold object (1 or 2) overhead with strait arms.
Odd objects can also be used for carrying, bear hug a sand or heavy bag.
Give carries a try during you next workout. Pick up something heavy, walk a certain distance, time or steps, and do that two or three times.
Have fun and try a variety of carries.
