There are different schools of thought on this question, but in my opinion it comes down to what your goal is.
- If you want to develop cardiovascular endurance – such as training for a 5k – then do your cardio workout first.
- If you want to gain strength or build lean muscle, then do your strength workout first.
For the general cardio enthusiast who wants to be able to do a long-term, sustained cardio workout with ease and comfort, it may be best to perform the cardio workout while the muscles are fresh. An appropriate workout might be to perform the cardio portion first, then progress into a light strength program working all the major muscle groups involved with that activity (walking, jogging, biking, swimming, etc).
If your primary goal is strength/build lean muscle, it would be best to do the strength component of your workout first. This allows the muscles optimal energy to complete the workout at the highest level and without early fatigue. Performing the cardio work right after the strength workout can also help with recovery by removing any waste products accumulated by strength training and by supplying the muscles with oxygen and nutrients.
Regardless of which you do first, it is important to warm-up to prepare your muscles and joints for the workout. The best choices include mild cardio exercise such as walking on a treadmill, or dynamic movements such as calisthenics.
