Beyond Combo Callouts: Strength, Footwork, Rope, Bag and Sparring

A phone propped against a water bottle. A voice says “1, 2, slip, 3” and someone in a garage throws it. Thirty seconds of that in a clip online, or a glimpse of it on the bag next to yours at the gym, and you get the idea instantly. That’s how most people find the Shadow Boxing App: they see it call out a combo and someone react to it.

We’re not going to pretend otherwise. Reacting to callouts is the core of the app and it’s what most people love about it. But if that’s the only thing you do with it, you’re using maybe a third of what’s in there.

What a real boxing class looks like

Think about the last class you took at a boxing gym, or the one you’re picturing if you’ve never been. It doesn’t start with the coach shouting numbers. It starts with the rope. Then some shadow boxing while the coach walks around fixing stances. Then a technical block where everyone works on one thing, maybe the jab, maybe slipping. Then bag rounds, pad rounds for the lucky ones, and a conditioning block at the end that everybody dreads. If it’s that kind of gym, some people glove up and spar.

Combos get called out during a chunk of that. Not all of it. A good class moves between cardio, technique, footwork, power and conditioning, and that mix is what makes you a better boxer rather than just a sweatier one.

That mix is what we’ve been building toward for years. The target has always been the same: get as close as possible to the workout you’d get in an actual class, with your phone standing in for the coach.

Everything that isn’t a combo callout

Here’s what that looks like in practice. These are rounds that exist in the app right now, and none of them are “throw this combo when I say so”.

Warmup, mobility and cooldown

The guided warmup runs before most workouts and adapts to what’s coming. The cooldown has different breathing exercises. Neither of these is a combo, and both are things a class does that most people skip at home.

Strength and cardio rounds

Open the 20 Minute HIIT Workout and somewhere in the middle you’ll hit a round of burpees. The coach on screen is doing them next to a heavy bag, the instruction is to keep going at your own rhythm, and the timer is green because this isn’t about reacting to anything. It’s about not stopping. Other rounds pair a squat with punches, or high knees with a jab-cross, so your legs are burning while you keep your hands moving. This is the conditioning block from class, except it’s spread through the workout instead of saved for the end.

Technical rounds on one thing

A coach will often say “this round, jab only”. The app does the same. Focus on the Jab is a full round where the only thing you throw is jabs, at different rhythms, so you actually pay attention to how it leaves and comes back. The Defense Drill is the same idea for slips and rolls: no punches at all, just getting out of the way. The Counter Punching workout flips it around. Every callout starts with a defensive move and you answer it with a punch, which is how counters work in a real exchange.

Footwork drills with no punches

Guided Footwork rounds call out directions, pivots and L Steps, and that’s it. You spend the round moving. It sounds easy until you do a full three minutes of it and realise how much you’ve been standing still during your combos. We put a lot of thought into how the app decides which way you move, because a round of footwork should feel like a drill, not a random number generator.

Jump rope, including rope on the floor

The jump rope workouts cover the obvious stuff, like the boxer skip and side swings, with the difficulty adapting to the level you set. The part people don’t expect is when the app tells you to lay the rope down. You make a line or a circle on the floor and the coach calls out steps over it: lead foot across, back out, jab on the beep and change direction. It’s a footwork drill disguised as a rope round, and it’s one of the better ways to practice stepping in and out without a partner.

Heavy bag

Bag rounds are their own thing in the app, and they’re not just “the same combos but hit something”. Bag Explosiveness is built around short bursts at full power with proper rest between them. Muscle Memory on the Bag repeats the same combination over and over until you stop thinking about it. The virtual pad work rounds call out a pad-style sequence so the bag feels like mitts. We reworked the whole bag section recently, and it’s now the biggest category after shadow boxing.

Speed ladder

If you have a ladder, the app has rounds for it. Some are pure agility, like fast feet or the forward straddle. Others mix punches in: a jab as you step through each rung, a 1-2 then an L Step out the side, a 1 followed by a block. The speed ladder workouts came out last month and there’s a program to get you started if you’ve never touched one.

Sparring, if you have a partner

This is the one nobody expects from a phone app. The guided sparring workouts give both boxers a rule for the round: jabs only, defend with slips. Or one person is Boxer A and only works the body while Boxer B only counters, and the roles change as the rounds progress. It keeps light sparring light and gives it a purpose, which is what a good coach does when they run sparring in class.

It all comes together in one workout

The point isn’t that each of these exists on its own. It’s that a single workout mixes them the way a class does. Open the Fundamentals workout and the timeline looks roughly like this:

• A guided warmup to start
• Focus on the Jab, then a metronome round, then pad work
• A recovery round of relaxed, continuous punches
• Defense rounds, then combos that mix in what you just defended
• A short cooldown

You go from technique to cardio to defense to combos in 24 minutes. You can edit any of it if a round isn’t for you, or build a session from scratch with the custom workout builder. If you don’t want to think about it, Quick Start asks how long you have and how hard you want it and picks for you.

So yes, it calls out combos

That’s still the heart of the app, and it’s still what we spend the most time refining. But next time you open it, scroll past the combo workouts for a minute. Look at the strength rounds, the footwork, the rope, the ladder, the bag, the sparring. A few of those rounds are in the free workouts, so you can get a feel for the range before paying for anything.

It calls out combos. It also does pretty much everything else a boxing class does, minus the drive to the gym.
