“Greasing the Groove” was a term that was coined by fitness trainer, author, and the man who introduced kettlebells to the United States, Pavel Tsatsouline. It’s a term that means not working your muscles to failure, but working them often. For example, instead of 5 sets of 12 repetitions of a specific muscle group where you go to failure, just do 5 reps or less. Take a long break in between sets. Sometimes up to 20 minutes or more. You can do the same for other muscle groups during this time of rest. This way, you’re not beating yourself up while still getting a high volume of heavy reps.
