Is there an alternative excersise? Had foot surgery last year and literally can not bend big toe on one foot. Sounds crazy lol.and it is!! I look all deformed when trying to do a back or forward lunge. I can make it happen but the form is definitely not right lol. I used to do walking lunges all the time and it definitely is challenging now…and hilarious to watch!! I do realize its one of the best for several muscle groups. So if there’s not an alternative its ok!
