FOR FITNESS TRACKING
Fitbit Alta Hr Fitness Wristband, £99, Argos ThIS device continuously monitors your heart rate, as well as tracking daily steps and calories burnt — supposedly to give an accurate idea of your fitness level. ‘ Lots of people wear these to ensure they do 10,000 steps a day,’ says Dr Sanjay Prasad, a consultant cardiologist at the Royal Brompton hospital in London. ‘A better option is to do regular, moderate- tointense exercise. This monitor helps because I aim to exercise while at least at 50 to 70 per cent of my maximum heart rate (220 beats per minute minus your age). ‘Pushing the heart rate this way releases antioxidants called nitrates from blood vessels, which help them to open up, therefore improving your vascular function.
