Cycling does build up your leg strength-- alot I would also strongly suggest that doing abdominal exercises and doing overall stretching exercises also is beneficial to keep muscles limber. A strong abdominal core set of muscles also helps for alot of sports, including cycling.

True cycling does not require strong hand and arm strength. As long as one is properly fitted on bike and arms, plus upper body not overstretched, it's a good start.

For certain cardiovascular improvement, physical stamina and lower blood pressure is a wonderful benefit of cycling also. One doesn't realize until one does other sports.

During the years of much more cycling, my blood pressure became quite low..enough to impress doctors.

That's great dancer, there are bike paths and routes in your city. It's a great way to get back on the bike without the stress of many cars close by.

Note: On my very first bike ride after not cycling for 12 years, I only went for less than 8 miles, on flat terrain. My thigh muscles were sore. But there after I became better and better.

I did cycle today..42 kms. Beautifully sunny and about 10 degrees F above freezing. We have no snow in our area.
