Tsatsouline is the founder of StrongFirst, a strength training organization dedicated to "the way of the strong." Their methodology treats every exercise as an ab exercise. For example, a heavy double kettlebell front squat is an example of "feed-back" tension, where the abs work to stabilize a load. A Hardstyle sit-up, on the other hand, is an example of "feed-forward" tension, where the mind directly commands the muscle to contract.

Power generated in your legs (like a kettlebell swing or a deadlift) must travel through your core to reach your upper body. A soft core acts like a broken link, leaking energy. A Hardstyle core ensures maximum force transfer.

Since 2012, Hardstyle Abs has been a go-to resource for strength athletes seeking a no-nonsense approach to core training. Here is how you can access this material today:

At the top of the swing, lock your knees, cram your glutes, and brace your abs as if preparing to take a punch.
