LESS is MORE
is a DISASTER!!
"...... more does not always mean better when it comes to the health benefits of exercise, and raise questions about the intensity and duration of physical activity at different times of life."
Research by German scientists found overdoing high intensity exercise may actually increase the risk of death from a heart attack or stroke in those with existing heart disease.
And a Swedish study, also published online in the journal Heart, suggests that young men undertaking endurance exercise for more than five hours a week may increase their risk of developing an irregular heart rhythm in later life.
After taking account of other influential factors, the most physically inactive were around twice as likely to have a heart attack or stroke as those who were regularly physically active. And they were around four times as likely to die of cardiovascular disease and all other causes."1
"Better verbal memory and faster psychomotor speed at ages 43 to 55 years were clearly associated with better cardiorespiratory fitness 25 years earlier." 2
For the scientifically minded:
Jay's BOTTOM LINE:
As always, consult with a physician before you start or significantly alter any exercise program.
You should be doing cardio 3 - 5 days a week for no more than one hour each day.
You also need to do strength / resistance exercises and flexibility and balance exercises.
And of course eat a balanced nutritional diet.
