I found that at the end of each set, my lower back hurt. I’m assuming my form isn’t correct. Can you give me some tips to keep in mind as I do the exercise?
It is really hard to say since I don’t know how you are doing them, so I don’t know how to instruct you to correct them. You can film a video of you doing the exercise and post it in the community page (form checks for exercises in the challenge are allowed to be posted in the community page), and we will give you pointers, tips and cues with form corrections based on what we see in your video.
