I haven't listened to the podcast but I have been doing High Intensity Training for a while now.
Whilst there is a lot of scientific evidence for this approach there are some modifications needed for the average trainee.
The research is clear that there is no difference between training 1 set and 20 sets in terms of gains. This is why HIT proposes doing 1 set to failure.
But I find that most people are simply unable to push themselves that hard in one set which is why multiple sets work best for the majority. High volume can overwhelm your recovery and lead to overtraining however so still limit it to no more than 4 sets for each of the 3 main compound movements (upper body pushing, pulling and legs).
Also in regards to training frequency, all muscle groups respond best to 1x/week frequency except abs which does better on twice a week so it's best to structure your routine with this in mind.
The extremely popular Leangains approach is quite representative of this modified HIT approach and I highly recommend using both the training and nutrition aspects of the method.
