Hi, when performing the exercise bicycle crunches does the leg have to be lowered flat.
Patient :Hi, when performing the exercise bicycle crunches does the leg have to be lowered flat (as close to the floor as possible) in order to burn calories or can the leg be lowered slightly raised from the floor (not as flat to the floor as possible). In other words is it the movement (contraction) of the legs in general that determines the calories burnt and not the leg being lowered as flat to the floor as it can be, and does the leg being lowered & raised from the floor from the lowest level (i.e as flat to the floor as it can be) determine the calories burnt or does this not really affect the number of calories burnt. Thankyou for your help and kind regards,

I understand your concern.
The lower the leg, more is the contraction on the abdominal muscles, and it should be flat over the floor. It definitely helps in burning more calories, but, once again, exact number can't be mentioned, as no such studies are available to prove this point.
Feel free to discuss further.
