Does the same apply to the front a arms?

no because that transfers weight forward, which in turn tranfers more force down on the rear whels.

think of it list this: Put your arm flat on a table (with your elbow down). try and raise your hand with your elbow still on the table. Now add weight/pressure to your hand and pick your arm up again (pivoting on your elbow that is still on the table). You'll feel more pressure on your elbow this time. 

i think i may have messed up explaining that but maybe you'll get the jist lol
