I travel for an hour by train every morning and would like to use the time to do some exercises, but I don’t want to draw attention to myself. Are there any exercises I can do that won’t make people think I’m mad?

Jason Anderson replies: I can’t guarantee that you won’t get funny looks, but here are a few things you can do on the train: One-leg standing: Try standing on one leg for up to 30 seconds. This is a great way of increasing your strength and stability, especially with the added movement of the train. One-leg glute activation: Stand on one leg about 50cm away from the wall of the train and place the other foot on the wall behind you. Push your foot into the wall for up to 10 seconds. Do six reps per leg. Calf raise: To reduce blood pooling in the lower body, do some calf raises facing a wall of the train. You can do onelegged calf raises to increase the intensity. One-arm press-up hold: Face the train wall and hold one arm out, pushing against it to create a rotational effort, improving your shoulder stability. Lift one foot off the floor for an added challenge. Just try not to kick any of your fellow commuters.
