“A six-month study of more than 120 adults in their 70s found that high-intensity interval training (HIIT) may offer a key advantage over other forms of exercise”
And also the one they are least likely to perform. Even people in wheelchairs can do resistance training, not so much HIIT. I see zero people over 70, including me, performing HIIT at the gym. I am sure there are some exceptional outliers.
I wonder why they don’t consider resistance training a form of exercise. Poor quality article overall.
Resistance training can be high intensity, especially with isometrics. Hold a plank or a bridge for two minutes and get a full-body workout. Get in a squat or horse stance and hold until you feel the burn. I also like the kitchen counter pushup, not reps but a static hold, which helps repair the shoulders.
