Weightlifting and Cardio in the same workout?

I am trying to lose some weight, as well as build some muscle. I heard that it is not good to do both Cardio and Weightlifting in the same workout. Is this true? I feel that sometimes even after I am done weightlifting i could squeeze out 20 minutes on the treadmill.|||It's fine to do both cardio and weight training in the same workout, provided you have the energy. We all agree on this one.





In terms of what order, there are two things to consider:





1.) Weight training requires more focus and energy than cardio, especially if you are working hard and heavy. Aside from a quick, light five minute warmup on an exercise bike or treadmill, performing cardio BEFORE weight training can have a negative impact on intensity during weight training. In other words, you'll be more fatigued, which means you may not be able to work your muscles as hard. This means gains and progress can come more slowly.





In fact, 2000 study at Southern Cross University in Australia found that men who exercised on a stationary bike for 30 minutes were weaker for up to six hours after their training session ended. So this suggests that you may want to hit the weights BEFORE lifting.





2.) There is also a theory -- and that's all it is right now -- that your body may burn more fat if you perform cardio AFTER weight lifting. Weight training depletes muscle and liver glycogen more quickly than cardio, so when you perform cardio after your weight training, when less glycogen is available, your body may burn more fat during cardio. However, the jury is still out on this. It's not clear which sequence causes the greatest fat loss. Research suggests that doing cardio first results in the greatest increase in post-exercise metabolism. However, weight training first appears to increase hormones that speed fat use (specifically, growth hormone, epinephrine andnorepinephrine.)





Lastly, 20 minutes of high-intensity interval training (HIIT) immediately following your weight training may be all of the cardio you need to strip off fat. There is a growing body of scientific data that suggests that HIIT training is very effective at burning fat while preserving lean tissue.





Bottom line is try one approach for 30 days and the switch to the other approach for the next 30 days and compare results. You need to find the right mix for you.





Best of luck!|||Its fine to do both.





For weight loss, id do the cardio before the lifting- at least enought to get your heart rate up to a target rate, that will help you burn calories while lifting.|||i definately agree with the doing cardio works outs first, and stretching. getting your heart rate up isnt exactly an important aspect of weight lifting but warming youre muscles up definatley is.


run your treadmill time, stretch out your body then do some reps, you can do cardio every day without breaking your body down, but remember to make sure you only do the weights every other day for upper body.|||of course you can do both. you should always do cardio first. it warms up your muscles and raises your heart rate. then lift. always only part, maybe arms monday, legs wed and, shouldters and back on friday. with cardio each day. good luck!


i've had a personal trainer for 3 years and he gets pissed if i just lift and skip the cardio. :)
