Increase intensity
Intensity builds muscle. A lot of the techniques mentioned in this article increase the intensity of your workout. Drop sets, supersets, negatives and slow reps are all classic examples. Other ways you can increase the intensity of your workout are decreased rest times, circuits, forced reps etc. When you’ve been using the same routine for a while it’s easy to get stuck in a rut, you think you’re training hard but your intensity level has been dropping slowly without you knowing it.
