How long should your cardio workouts be and should you have a combination of cardio and weight training everyday? Or should one day be strictly devoted to cardio and other days to weight training?
The ideal cardio workout should be 30-60 minutes or even longer if you have the time. However studies show that you can divide the time up in 10-15 minute segments throughout the day. It is perfectly fine to do cardio and weight training on the same day as long as you have enough energy to get a good workout. It is also just fine to do cardio one day and weights another as long as you are consistent in your training. Cardio can be done everyday but your muscles need rest for a day after weight training so they can repair. If you do cardio daily, try to mix up the intensity so that you are not going hard and furious everyday. For example, you might do a cycle class 2 days a week and a kick box class on another day but then take a long walk around a lake or on the tread mill the next day and then swim the day after that. Then you can hit it hard again. As an instructor I have taught a weight training class two days in a row but then I give myself a day or more to rest afterwards so that I still get the benefit of muscle rest and repair.
Most of us shouldn’t get too wrapped around the axel about time and order. As long as you are consistent in your workout and give you body time to rest, you will be fine.
