sometimes i go to the gym. i prefer to go to the court, or to the field, or to the mountains, or the the beach, or to the track, or to the trail. but sometimes, i go to the gym. and when i do, i HIIT it.
in the words of Eric Salvador, NASM, NSCA, head instructor at The Fhitting Room in NYC, “A high-intensity workout increases the body’s need for oxygen during the effort and creates an oxygen shortage, causing your body to ask for more oxygen during recovery.”
in the words of vanessa, fitness fanatic, athlete, and head word splurger at thefirst2hours, HIIT (high-intensity interval training), is a training technique that forces you to give all-out, one hundred percent effort through quick, intense bursts of exercise.
