Is biking really reduce fat from thighs and make them not touch ? Or it transform fats from thigh to muscles and so they will stay at the same size ?
From this link, it seems that biking is useless:
Research suggests you should be burning at least 8,400 kilojoules (about 2,000 calories) a week through exercise. Steady cycling burns about 1,200 kilojoules (about 300 calories) per hour.
If you cycle twice a day, the kilojoules burnt soon add up. British research shows that a half-hour bike ride every day will burn nearly five kilograms of fat over a year.
