Absolutely bike riding is a good form of exercise. You can ride a bicycle just about any time of the year in many locations and it is a relatively inexpensive activity. Cycling increases muscle strength and tone of the legs, cardiorespiratory function and burns calories.ny exercise that makes you move is a good exercise. Biking is one of my favorite exercises. My knees never hurt no matter how many miles I pedal. It is easier on the joints than running.
The U.S. Air Force title Sergeant (E-4, equivalent to an Army or Marine Corporal and Navy/Coast Guard Petty Officer Third Class), commonly and informally referred to as buck sergeant, was used beginning in October 1967 in the hope that the prestige of being an NCO would increase the re-enlistment rate. The title was phased out again in the 1990s.
The U.S. Air Force became a separate service on 17 September 1947, and on 13 January 1948, Scott Field was re-designated as Scott Air Force Base and the 3310th Technical Training Wing assumed host responsibility from the 3505th Army Air Forces Base Unit.
