It's a common sight in many gyms.
As soon as people finish their lift, they head directly to the treadmill for 30 or 40 minutes of cardio.
In theory, it makes sense: while strength training movements largely target the anaerobic energy systems, endurance exercise largely target the aerobic energy systems.
Performing both in the same workout seems like a recipe for ultra-efficient training.
However, recent research has found that performing cardio immediately after strength training significantly impairs muscle gain. This is a classic case where working harder is not working smarter.
The takeaway: if you want to see big gains from your strength training, the last thing you should do is hop on a treadmill for a cardio session immediately after you finish pumping iron.
