What are everyone's fitness routines? How do you like to exercise? How do you track progress if you track?
Something I find very useful:: Apple Watch has a feature that tracks your VO2Max while walking and running OUTSIDE. I don't know how precise it is, but as a tool for tracking relative improvement it is fantastic. I find it motivating especially if social events (vacations etc) cause me to skip my normal routines and the watch highlights the corresponding decline in fitness. I am motivated to regaining my prior level and then higher. It basically measures your body's ability to process oxygen so your heart, lungs and muscle. It takes into account your age and body characteristics like height and weight as well. If you are competitive ( I am) then it can be fun to share this data with friends of like minds.
Apple has a really nice write up of it here:
https://www.apple.com/healthcare/do...h_to_Estimate_Cardio_Fitness_with_VO2_max.pdf
From the paper:
"Definition
VO2 max is the maximum volume of oxygen an individual can extract from inhaled air and consume
through cellular metabolism. As such, VO2 max is a good overall indicator of cardiorespiratory fitness
(CRF) because it incorporates multiple organ systems and is influenced by a number of factors at various points along the pathway, from respiration to end-organ oxygen consumption.1 VO2 max values are
typically normalized for body mass and reported as milliliters of oxygen per kilogram of body mass in one minute (ml/kg/min). They normally decline with increasing age and, at a population level, differ across biological sexes.2"
Don't let the paper make you think using this feature or tracking it is hard. It is VERY easy as the watch will do it for you without you even asking. It will then show your score and track progress for you in the Health App on your iPhone. Simply record your walk/run on your watch and that is all you have to do.
