Should I Exercise Every Day or Every Alternate Day?
There isn't an easy answer to this question. It depends on what you want to achieve. If general fitness is desired then every second day could be beneficial as it allows 48 hours of recovery time between each session. If weight loss is the objective then a daily exercise regime that burns off 300 calories or so would be desirable. Perhaps if both weight loss and strength gain is desired then alternate days of cardio and weight training could do the trick.
As this blog targets the mature individual facing the imminent prospect of old age the answer to the question should be relevant to this group. I don't know the answer. I do think that every second day is likely to result in missed days that extend the period between workouts. Generally for those pursuing 'active survival' exercise should be obsessional as diet should be also. Exercise everyday and then some unless physical injury is being experienced.
