The short answer is yes! Jogging is a simple yet powerfull way of becoming more faster is the water. You would find yourself getting tired fast when you doing your swimming drills, and the reason for that is because you havnt strengthened the heart muscle
Remember that the heart is also a muscle, people tend to forget that for some weird reason. The reason i can boldly claim that jogging will help you swim faster is because i am a qualified life saver, and in my training i experimented in different training methods. I always wondered howcome im so tired after i finished a 400m swim yet the other guys are still fresh ready to go another 400. Then i decided to go jogging in the afternoons and do swimming in the mornings, and i saw a huge difference.
SO THIS IS HOW I TRAINED.
I would go to the grounds in my area, and start off doing just 5 laps 3 times a week. Then i would do my swimming 3 times a week. So i would alternate days. My swimming drills would change frome day to day, in another article i will break dowm my full swimming drills if that is what interests you. I never do this everyday because you need to give your body a break if you want to see difference, remember is quality over quantity.
To my surprise i started swimming alont faster and more longer, i could eventually keep up or lead the other guys, i wasnt getting tired so fast anymore, not because running and jogging made me faster in ther water no, but because i strengthened the heart muscle.
So if you find yourself struggling to maintain a consistent pace in the water, go jogging, start out small, give it a shot. If you want a article of my swimming program for coaching, swimming faster or longer or even beating the clock, then comment down bellow.
