As I may have alluded in previous posts, I enjoy coupling my strength training with cardio as a warmup. For the most of my workouts (leg day is an exception), I would run before lifting because it is a great warm up… However, this is solely in ideal situations.
As winter approaches, the mornings, especially within the optimal 7-7:45am range, have been dark because the nights are getting longer and the days are getting shorter. Running in the dark is scary. No further explanation needed. Personally, this change has been awful. I am so tired after lifting and I have no motivation to run, let alone run inside on the treadmills. I prefer not to run inside before lifting because I get REALLY sweaty and having to lift for another hour afterwards would be torture for everyone around me.
To remedy this, I have been swimming a lot more. I jump into the pool at 6am and although tough, its very enjoyable afterwards. It’s a great way to warm up your whole body and you can’t even tell you are sweating! Also, I am more energized for my lift because the water is slightly cold so it does the job of getting me to wake up. Finding this alternative led me down the research path to see what’s more beneficial: cardio before or after lifting?
Cardio before lifting
This combination entails doing something that will get your heart pumping (like running, biking, swimming, etc.) followed by an anaerobic lifting routine. The American Council of Exercise detailed a variety of situations where cardio first is ideal. If the goal is endurance or training the upper body, leave the lifting for later. This can also happen if you don’t have any particular strength goal in mind. Basically, cardio will fatigue your body quite a bit, so you want to make sure that whatever follows this high intensity workout is something that will be a little “lighter” on the body. An interesting, but obvious, finding that I came across was that running has worse implications on lifting than cycling. Yes, running will break down more muscle, making lifts harder.
Cardio after lifting
If the overall goals are to lose weight, improve strength, or train lower body groups, they are most effectively met when lifting is first followed by cardio. Trying to reach any of the goals above takes a lot of energy and strength out of an individuals. For example, my leg day takes around 1.5 hours and it couples many heavy-weight sets with lighter drop sets that have more repetition. My goal is to improve strength and I find that my leg days are best when I DO NOT run prior to the lift. If I do run, I find myself cutting out exercises and shortening sets because of fatigue. Maybe it is in part my fault because I run longer distances (5-7 miles), but that is the distance where I feel the best. Regardless, the general notion is cardio second if you plan on exerting A LOT of strength anaerobically. Not to mention, my runs are better after lifting as well, consisting of more miles at a faster pace:
Run then lift Lift then run
Pretty much, whether cardio is first or second depends on the goal and the person. Some people may need to cardio as a warm up before a heavy leg day. Others (like myself) may find it as a setback due to tiredness and pain. As the seasons continue to change and my routine changes as well, I intend to test out other forms of cardio or perhaps more spaced out intervals of training to ensure maximum strength improvement.
