Reps to failure or leave a few in the tank?

The age-old question, how much work do I need to do to achieve the desired result? The goal should always be the least amount possible. But there is so much data out there that supports training to failure every set to get stronger. There is also information out there that shows keeping repetition velocity high throughout working sets is important. So what should you believe? This episode dives into the latest research comparing "reps to failure" to "leaving a few reps in the tank." I think you will be surprised with what the results reveal as it relates to total work done, muscle damage, and repetition velocity between these two scenarios.
