How To Do Crunches

We don’t have to overcomplicate this exercise but there are a few things you have to do to feel your abs work properly.

  • Have your hands directly over your shoulders
  • Open and close your ribs after each rep
  • Exhale every time you crunch to help with activation
Here is a video tutorial of what I’m talking about

Simple right? The key is to do more of them* 🙂

It’s common when you are first starting that you may feel this in your neck as well so if you need to

support your neck just put your hands behind your head.

*The key do getting abs or any results for that matter is variety and progressive overload training. Simple put just put a little variety into your training.

Crunches Vs Sit Ups

Crunches and sit ups are two foundational exercise for abs and I’m a HUGE believer in mastering the

basics/foundational movements first.

It’s the same reason why we offer the harder and easier button in our fitness app.

Whether you are doing a push up, a crunch, a sit up or any exercise within our app when you want to

challenge yourself you can simple click harder…

…just like I would do with you in a personal training session.

I have two different sit up variations for you to try.

One really hard one and an easier version:

Variation #1

Straight leg sit up (harder variation)

This is a very challenging sit up.

The strength required in your core, shoulders and midline is going to be challenged.

But that’s why you are here, give it a try!

Variation #2

Butterfly sit ups are another variation (easier one)

That’s my wife Katie (she is a bada**)

That’s where the name K Squared Fitness comes from by the way (Kevin & Katie) anyway…

…butterfly sit ups are a little different than what you might have thought of when it comes to sit ups.

You were probably visualizing having your feet locked into something we would do that when I was in the

military and there is nothing wrong with that.

The benefit of the crunch vs the sit up specifically the butterfly style is that hit your entire core

ESPECIALLY if you control on the way down.

Give it a try!
