Question: Asked by a female:
Will using a treadmill on an incline make my leg muscles too big?
Answer:
"It is a common misconception that walking or jogging on an incline
will build up your legs", says Heather Rider, a Reebok master trainer.
"A very small percentage of women may be prone to developing large
muscles if they work against HEAVY resistance, however most women don't
have enough testosterone for that to happen, and waking uphill typically
doesn't offer enough resistance to lead to massive muscles anyway. You may
notice tone where there was non before, but this is a good thing. Plus your
walking or jogging on an incline will burn more calories because your body
has to work harder and recruit more muscles."
Lisa adds:
Also, for calorie burning, every 1% incline increases the calories you burn
by 10%. A 150 pound person burns 100 calories a mile; with a 1% grade they
burn 110 calories a mile. 2% grade 120 calories etc.
10% grade = 200 calories a mile for a 150 pound person.
Just do a ratio and proportion to figure out how much you burn per mile.
FYI- 175 pounds= 116 per mile
200 pounds 133 per mile
125 pounds = 83 calories per mile
