I am a 42 yr old male. About a month ago I finished a running program that has me now well adapted to running 3 times a week for half an hour (the famous C25K, non-commercial and freely available at www.nhs.uk). I have done no other exercise in the last year.
My body seems to be craving more physical exercise and I have started mixing different activities that (hopefully) don't overlap: swimming (above 700 m in each session) and callisthenics (twice a week, a simple pull/push routine called "New Blood").
I am afraid of injuring my heart or something. Is it bad to exercise almost everyday at my age? This has been my last week:
Day 1: I swam 750 metres
Day 2: Calisthenics (Push)
Day 3: Again 750 metres
Day 4: Rest
Day 5 30 minutes run
Day 6: Calisthenics (Pull)
Day 7: Swimming 750 m again
The sudden increase in exercise has me sleeping well, with good appetite and very good humor (yep, endorphins release or something). But I don't know if I am risking a heart attack or something.
Note: I had a cardiologist check about a year ago and everything was fine.
