Ask a Trainer: Why can’t I just do cardio?

While cardiovascular training is great for building strong hearts and lungs, it doesn’t provide the stimulus your body needs to build bigger, stronger muscles and bones.  Why? Our bodies adapt fairly quickly to the load we ask them to move; unless you’re gaining weight, you legs will always be subject to the same load and moving that load through the same, limited range of motion.  Adding strength training to your program allows you to:

  1. Increase the load on your legs
  2. Change the range of motion you move your joints through
  3. Target muscles that you don’t typically use during cardiovascular training
