6 workout tips from dumblittleman

I know a lot of these things have been mentioned before, not sure about the weight before cardio thing since I recall hearing the reverse before too.

i think it's a good list, but i think the weights before cardio part isn't really accurate.

"However, trainers, serious athletes and bodybuilders do weights first: this way, your heart rate goes up and when you lift, your body is in more of a fat burning mode."

assuming i remember my exercise physiology class right, we don't use fat to power our muscles when doing anaerobic exercise like weight lifting. so you're not going to get into a "fat burning mode" by lifting weights first.

it's my opinion that unless you're planning on an hour of cardio, doing something like HIIT, or seriously body building (or training hard core for something specific), it doesn't matter which you do first.

if you're really training for something specific, then it's probably best to warm-up and then do whatever is specific to your goal (ie. if you're body building, warm-up then weight lift; if you're training for a marathon, warm-up then hit the track).

ymmv

Weight training kicks your metabolism into high gear for around two days. In addition, weight training burns off the fuel in your muscles alot faster than cardiovascular training. Because of this, it is more productive to preform your cardio after weight training instead of beforehand. Since the fuel is burnt by the weight training, whatever cardio you do afterwards will be burning mainly fat and carbohydrates making it much more effective.

Weight training does not necessarily consume more calories or energy from the muscle, but it consumes it at a much faster rate per minute. The problem is the byproduct of this is lactic acid, upsets the ph balance of the bloodstream and shuts down the body in selfdefense. So aerobic exercise does consume energy at a slower rate, but is able to be sustained longer.
Weight training does work more effectively with glucose and carbs. Normal weight training and diet is all carb consumption while exercising. Aerobic exercise blends together fat and carbs for energy. The harder you do aerobics, the more the proportion shifts to carb consumption. If you burn up your limited supply of carbs with aerobics, your weight training workouts will suffer. If you weight train first, you can still do aerobics, albeit at a slower, more fat consuming pace.
