When you want to work your core, back, and arms in one go, then a hanging knee tuck needs to be your go-to move. This seemingly simple bodyweight exercise requires just a pull-up bar and your weight but it can elicit some serious burn.
I’m all for an abs workout and love anything that sets my core muscles on fire. So why would I not agree to a hanging knee tuck challenge? For this, I opted to do 100 hanging knee tucks every day for a week.
