How To Do A Back 2½ Tuck (205C): Readiness, Arm Circle Timing, and Kicking At The Board

Back 2½ tuck is a big dive and there's a lot to cover.

I'm going to start with the prep work and how you know you're actually ready, then get into the more advanced material in the second half. If you're already doing this dive, you can skip to the more advanced ideas below.

A lot of people watching will be attempting it for the first time, so I want you to understand both what goes into the preparation and what it takes to make this dive as good as it can be.

How Do You Know You're Ready?

Your back 1½

You should be good at coming out of a back 1½ tuck on both one meter and three meter. If you aren't comfortable with back 1½ on three meter, you probably shouldn't be trying back 2½ yet. There are exceptions, but that's the general rule. 

This is because doing 203c on 3m gives you comfort on the start and teaches control for the kickout location and how to hold hollow or flat as you go for the entry.

What you want specifically is a strong kickout on your back 1½ on one meter, finishing high, knowing exactly where you are. That's what sets up your spotting.

Your back double

You also need a very good back double on one meter. I don't think any coach would let you take this up without one. Here's what a good back double looks like:

• Great balance on the takeoff. Not sitting back too far, but not hipping in too much either, because you don't want to be too close to the board as you come around for that last flip and kick out.
• No head whip. A lot of divers whip the head back to get momentum going. That's a mistake. Do it on three meter and you'll fly back and get whippy on the entry.
• Smooth arms and a real C position. Arms through smoothly, hips driving into the C position (or banana position, whatever your coach calls it).
• Looking into the tuck. as your legs come up, your upper body is hollow abd you are looking down into where your legs are. this is a strong position to be in. Head back and archy is a weak position.
• Knowing where you are. You should see the water twice, or see the board twice, as you flip. That way your come-out is based on visual cues plus feel, not feel alone.

Diver Guy's Tip: The more you sit on a back, the easier it is for your legs to whip over on the entry. That's why this takeoff matters so much and why the leadups have to be clean before you go up.

Your First Attempts

Once you're consistently seeing your spots and your coach thinks you're ready, take some deep breaths and go for it. At that point it's a bigger mental struggle than a physical one.

The biggest thing I can tell you: be patient on the takeoff.

Most people rush the arm circle and lean back too much on their first few.

Honestly that's fine early on. You're getting it off the board and you'll have a coach on a call as backup. But the more you can force yourself to relax and pretend it's just a back double on one meter, the better off you'll be. If bubbles are available, use them.

The goal with any optional start is to make it feel like the leadup. Once the optional feels like the leadup, you're 100% comfortable with the dive. That takes time, because you're higher up, it's more nerve-wracking, and there are more flips, which means more chances to miss a spot or botch the out.

Why You're Falling Back: Arm Circle Timing

Here's a big difference between someone who's been doing this dive for a year or two and someone using it as a drill for back 2½ pike or back 3½. It's the timing of the arm circle.

Newer divers are still falling back. They're not getting full force from the board because they aren't staying on top of it long enough, so they finish low and don't have time for a strong come-out and a lengthened entry.

Watch the first advanced example in the video. As she peaks at the top of that last oscillation, her arms start moving early, then connect with her shoulders as she comes up for the final standup. That's what sends her back.

Diver Guy's Tip: Anytime you move your arms too early, you initiate your C position too early. And if the board is still down when you hit that C position, you're going to fall back. That's why pro divers wait much longer to start the arm circle before standing up. They stay over the board as long as possible because they want to leverage the board, which is far stronger than they are.

The consequence compounds. Because she falls back, her legs have to travel further to reach her upper body in the tuck, which leaves her in a bigger position, which makes her flip slower. She still finishes and gets an entry, but she has to rush her hands back and never fully locks out.

The In-Between Phase

The second example is doing the dive as a drill with a double bounce, which is completely fine. That's actually a great way to buy yourself extra air time to practice a nicer come-out. It helps you relax up there, and then you carry that experience back to a normal takeoff.

She gets her arms up well but is still falling back a fair amount. She brings her legs up in front, just a little early. You'd want to extend up longer so the board comes up higher and pushes you better. She gets into a great tuck and spots well, but still has a rushed out.

That's the in-between phase, and it's worth naming because almost everyone hits it. You're not finishing high enough yet to show off a strong legs-first out, but you also don't actually need to punch as fast for the water anymore.

You'll have transition periods on every dive where you're physically capable of performing at a higher level, but your habits keep you punching for the water like you have less time than you do.

Your technique or strength improved and your habits didn't catch up. You have to notice that and break through it, either with drills or just mental fortitude to rebuild the habit.

Spotting: Kick At The Board

The third example finishes higher but is still falling back a little, because balance is one of the hardest things in the sport to get. Same root cause: the arm circle starts on the way up, so they sit too much and the hips come off the board. Once the hips aren't over the board, the board shoots you out. They have a great connection and a great tuck, and they can kick for the board and look back well, they just get loose and throw the head back too much on the entry.

Spotting is a practice thing. Your spots shift slightly as you get better, but for the most part you're kicking at the board, and that makes this dive considerably easier than reverse 2½. You have something physical to aim at as you come around for that second flip.

Diver Guy's Tip: Look for the water, then track with your eyes up to the board. Based on how long it took you to get from one flip to the next, you'll know how to angle your kick to line up the entry.

Adjusting on the fly

Consistent starts are ideal but not realistic. Some starts really pop, you get a great hip drive and flip fast, so you have to come out and kick harder at the board a little earlier. Other times you accidentally sit too much, don't get as much force, and have to wait longer and kick higher than the board.

Making those adjustments only comes from experience. But be actively thinking about it, because that's how the experience turns into skill.

What the Best in the World Do

Take this with a grain of salt, because even pros doing back 3½ deal with a lot of the same issues you're dealing with on your back 2½ or back 1½. But it's useful as a target.

Watch the final example:

• Long and extended for the final press
• He drives down, and his arms start moving as he's going down into the squat, but his chest stays over the board the whole time
• He bends really deep into the squat, deeper than the other divers in the video. Most divers can't get that low because they get unstable or aren't strong enough yet
• His body stays over the board all the way through the extension. Hips still on top of the board into the C position
• He doesn't start lifting his legs until the board is just about flat again. Then he explodes into the tuck. Knees come up fast, arms go to meet them, and he pulls in as quick as he can

That last part is the key sequence: finish the extension, let the board push you, then it becomes a race to get tucked. The sooner you're in the tuck, the faster you flip. But it only works in that order.

Then look at the comeout. The time between tuck and knees fully extended is about a millisecond. That's how you stop rotation, and that's how you show the leg lines you're being judged on.

Commit To The Kick

Once your takeoff is under control and your spotting is decent, you'll feel confident enough to commit to the comeout. That's half the battle.

The stronger and more consistently you kick, the better your entries. Kick soft and your entry is soft. Build the habit of a strong kick and your entries improve even when you're short, over, or straight up and down, because you're tight.

The best way to learn this dive is by doing it. When you're ready, give it a send and worry about the advanced stuff later.

Good luck and I'll see you on the next dive! - DG
