So I've been trying to work on my abs without going to the gym (because no time). I've been getting sick of planks and I hate crunches with a passion, so I followed some 
advice and got an ab wheel.
The moment I saw some videos on how to use it, I'm like, "I'm gonna faceplant so hard when I try this". So when it arrived, I tested it and sure enough, faceplant. Obviously, my abs aren't strong enough to keep me up, so more strength and practice in that area would definitely help. But is there anything I can do in the meantime to get there? Some kind of half-rep or something to help me build up my core? Or should I just go back to planks and reverse crunches?
Thanks for the advice! It's all very helpful!
I am indeed doing in on my knees, aside from once or twice on my feet to see what it's like. Good call on the hanging leg raises, too. I've been using my pull-up bar quite a bit for my arms, so I'll just add the core to it as well. It's only been a day since I got the wheel so you're right that getting the balance is a huge part of it haha. I'll definitely keep your form advice in mind when I practice.
Sounds like you have the tools to succeed. You've got this.
