If I only have 30 minutes a day to work out

Quote  |  Reply
If I only have about 30 minutes a day to actually work out (on my lunch break after walking to the gym, changing, and then working out and getting ready to go back to work)...would it be better for me to do one day cardio and the next weights, and keep alternating, or would it be better to do 15 minutes of weights and 15 minutes of cardio each day??????

You'll have the best results if you focus on each in turn - cardio and weights on separate days sounds ideal to me :)

Well, take a couple of things into consideration. 1) how long is the walk to the gym and 2) what are you fitness goals?


Remember Fat burning doesn't start until after 15mins of exercise. So, depending on the how long the walk is, that may be sufficient cardio. Also, depending on your goals, I'd focus on cardio 3-4 days a week and a full body weight lifting program the last day(s). 

If possible, a class at the gym like kick boxing or yoga would be a nice way to change things up.

Good luck!


The walk is a 5 minute walk, the gym is in my building, just on the other side, through a tunnel, up an escalator.......

My fitness goal is basically to burn fat. I want to firm up all over and lose the layer of fat I have on my body- so I know that a combo of weights and cardio is important. I am just really concerned with gettting the most effective workout in my short timeframe.
Not sure if it's an option, and although I think it would be best to alternate as well (one day cardio, the next: weights), but yet another way to continually keep your body guessing would be to cross-train.  I did this a couple of years ago and had wonderful results.  I would run for about 60-seconds on the treadmill, hop off, and do 15 reps on a machine, hop back on the treadmill, run another 60 seconds (to 70 seconds), hop off and do another 15 reps on the same machine.  I would end up doing this for 30-minutes, and would end up doing 3 sets of 15 reps ona total of about 4 different machines (body parts).  The workout was both cardio and weight-training, but burned the max amt of calories, since my heart-rate was UP even while weight lifting due to the constant running in-between.  I hired a personal trainer and he would do this with me regularly. 

what a cool idea switching from treadmill to machine like that!

deffo going to try it thanks for posting :D
