A personal trainer says these are the exercises to do if you’ve got no equipment and only 20 minutes to spare—here’s my verdict

A woman exercises on hands and knees in her living room. Her arms are straight, hands on the floor, and her right leg is bent so that her knee and toes are on the floor. Her left leg is also bent but kicking upwards towards the ceiling. behind her we see a couch, shelving and plants.

The most common barrier to a consistent fitness routine is time. Some beginners even assume a workout doesn’t count unless it’s at least 30 minutes long.

But short, regular bursts of activity can actually improve your cardio fitness and overall health.
