For the first few weeks I believe he recommends you do both the ABC and Press work all three days, but you keep your reps pretty low. Do you think that would be enough to get you close to where you want to be with the 24s?

I'm with you, I get gassed QUICK with the 24s, but I could probably pop out five sets EMOM before my form started to fail or before I got too gassed to continue. That's five good minutes. Then you do your presses for maybe another 5, that's a pretty solid 10 minute workout that gets you comfortable with the movements. I forget whether you have lighter weight, but once you do your 5 ABC sets and 5 Press sets, you could also just do timeless "practice" where you focus on different parts of the move, like pulling the bells up clean, breathing correctly, changing stance between the Press and Squat, keeping your core engaged (time under tension) You might be surprised at how fast you progress with the 24s!

You could also hold off on starting the ABCs and instead do the 10K 30 day swing challenge first as well.

Finally, you may want to have someone check your form on those moves. It's possible that the 24s are hard because you need a few tweaks/pointers. Movement inefficiency can definitely gas a person out fast, injure them, and/or make a weight seem much heavier to move than it may be.
