single leg arch ups and back lever

today I tried the single leg arch ups and found them a great exercise for my lower back . I'm wondering if single leg arch ups would be a good exercise for developing back lever core strength? I work out at home and I have places were i can train front levers easily but not back levers.

Sure, it's in the core section. It's taken me awhile to post on this.

I can't really train BL at home either because of where I do my pullups and FL ( hanging from the hole going to the attic ).
