Yeah really the main importance is to count the calories of what you eat. Even if i do eat some unhealthy foods i usually work out extra hard the next day. Oh yeah if you guys don't like running here is a good way that helps me sweat allot of crap out and trim up too. This is a treadmill workout.that is ridiculous
Hop on the treadmill
set it to manual...
set the time for 15mins MINIMUM! (if your just starting out)
set your weight etc..
set the incline to 10.0 (pretty much like waling up a hill)
set the speed to 3.0 and start
That alone right there will help you shread and sweat off that weight. Try not to hold on to the rails... just walk on it until the time is up. I always do this before i lift but i set it at 45mins. The best ideal way to do this is to atleast go for 1hr.
if anything a pre lift cardio should be only done to warm you up (functional movements like pushups squats shadow boxing and dynamic stretching are more optimal)
better yet don't do cardio hours before or after lift session, if you have no time do it after not before the lift
the reasoning is you want to put full effort in what you do but if for purely appearance you can get away with cardio after lifting if you do it reverse your lifts would suffer
