Sorry dude, but you're the one who's sounding like you don't have anything constructive to add. If you want to put forward a fairly controversial proposition demonstrating that cycling is in fact a strength sport, then you should be able to a) bring some evidence, and b) be prepared to defend it robustly. It seems that you are prepared for neither.
OK - I will give you some of my experiences provided by my training
a - best marathon at 43 yrs of age - 3hrs : 32mins
b - at the age of 50 i walked 50 miles on my birthday
and continued doing this up to the age of 64
c - at the age of 51 to raise money for a local cause
i walked from Leyland in lancashire to Bowness in
the Lake district and back again - 110 miles in 2 days
d - at the age of 52 i walked from leyland to the top of Scafell
Pike and back again - 138 miles in 69 hrs
e - every year from the age of 70 i have cycled twice my age
on my birth day - i am 73 yrs of age
f - I am currently training to raise money next year on behalf
of a young woman who is terminaly ill by cycling 500 miles
in 7 days - finishing on my 74th birthday
I rest my case - the proof of the pudding is in the eating !!!!!!
