As someone who isn't a fan of sit-ups I love it when I find a strength workout that really challenges the core without the controversial move. And certified trainer Natalie Wilson has created exactly that with a five-move kneeling upper-body workout she posted to Instagram. No, it's not an explicit core workout, but as Wilson writes in the caption, "kneeling activates the core really well," something I've seen Sweat trainer Britany Williams say, too.
You'll also see that Wilson combines two movements in one for each exercise—a technique I use with my personal training clients. While this style of training might feel a bit intimidating, I believe it's a good way to get stronger without investing in heavier weights. Two moves in one will make the exercise more challenging so you're more likely to see progression in your strength, plus it avoids having to do the same arm exercises over and over again.
