Rhidiculous Christmas Core Challenge
DAY 20🎄

All about that ANTI EXTENSION today! Just three simple moves that hit your core in different ways when you slow them down and actually stay in position. If you rush this, you’ll miss it. If you move with control, you’ll feel everything.

Oh and did i mention, it’s a one and done day too?? One round, thats it!

1️⃣One round only
▶️45 sec per move
↔️15 sec to transition between moves

⭐ Pilates Toe Taps
This is anti-extension core work. Your job is to keep your ribs down and low back pressed into the floor while your legs move. Slow taps > big range.

⭐ Bear Stance Plank
This one is anti-extension + anti-rotation. Knees hover, spine stays long, and everything works together to keep you steady. Press the floor away and don’t let your torso shift.

⭐ Rocking Plank
This is still anti-extension, just with movement layered in. Small rocks, steady body. If your ribs flare or hips drop, make the range smaller.

For those of you who read the full caption…
🎄how are we liking RCCC this year??
Better.. worse 🙈 than expectations or past years???

Rhidiculous Christmas Core Challenge
DAY 19🎄

Today is one of those sneaky core days. Nothing flashy, but everything works when you stay controlled.

The goal is holding good position while your core does the work, not muscling through it.

⛵️Boat holds challenge your ability to stay braced up front, and side planks light up your obliques by asking you to stay tall and steady.

2️⃣Rounds
▶️30 sec per move/side
↔️10 sec transition
⏸️20 sec rest between rounds

⭐ Boat Hold (Leg extension OR Toe Taps)
⭐ Side Plank Hip Dips (bodyweight or weighted)

You have options/different levels for both of these from me today.

Pick the version that lets you move with control.

Only 5 more days of Rhidiculous Christmas Core Challenge after this one!!!

Are we happy to almost be done?? Sad???

Rhidiculous Christmas Core Challenge
DAY 18🎄
Progression Play Day

Today’s core work is all about control. I’m showing a few different ways you can add weight to dead bugs so you can pick what feels right for you, without changing the goal of the movement. If adding load makes your form fall apart, that’s your cue to scale it back.

3 rounds
▶️30 sec per move
↔️10 sec transition
⏸️20 sec rest between rounds

⭐ Dead Bug Pick Your Load
You’ve got options here:
· Ankle weights on the ankles
· Wrist weights on the arms
· Both wrists + ankles
·Or holding a light dumbbell(s)

Whichever you choose, the rules stay the same: ribs down, low back pressed into the floor, slow controlled reps. The weight should never pull you out of position.

⭐ Flutter Kicks
Bodyweight is perfect here, but if you want more, you can hold a light weight straight above your chest for extra demand. Small kicks, steady breath, and adjust leg height if your low back starts to lift.

This one really rewards patience and intention.

If you rush it, you’ll miss the reward!

Final stretch here now friends…. How we feeling overall???

For those who are back from past years, has this year been easier, harder or about the same in your opinion compared to past years??

Rhidiculous Christmas Core Challenge
DAY 17🎄
Lower Core Control Day

Today is all about slow, intentional lower core work.

We’re using two leg-lift variations that look simple, but absolutely demand control when you do them right. Ankle weights are optional, but if you use them, the goal is still clean reps… not swinging your legs around.

🔄3 rounds
▶️30 sec per move
↔️10 sec transition
⏸️20 sec rest between rounds

⭐ Diamond Leg Lifts
Heels together, knees open. Think posterior pelvic tilt first, then lift. Small range, slow lower, and keep your low back calm on the floor.

⭐ Straight Leg Lifts
Long legs, ribs down, and no arching. Lower only as far as you can control, then pull the legs back up using your core, not momentum.

This is one of those days where slower = harder. If you feel this in your hip flexors, shorten the range and lock your ribs in harder.

DAY 16🎄
LADDER DAY🪜

Two moves today, and we’re running them through a clean little ladder. The rep count drops each round, so the goal is control, not speed. Bent-leg jackknives and ab bikes hit your entire midline when you move slow and intentional… and this ladder format makes every rep count.

🪜Ladder🪜
10 reps each
8 reps each
6 reps each
4 reps each
2 reps each
Done ✔️
(* for Ab bikes R+L = 1 rep)

⭐ Bent-Leg Jackknives
Reach through your trunk, not your arms. Slow lift, slow lower. Think ribs to hips with every rep.

⭐ Ab Bikes
Rotate from your ribcage, not your neck. Elbow to knee because your trunk is turning, not because you’re pulling. Keep the hips steady and smooth.

This ladder is 🌶️ and such a good way to start (or end) the day.

Rhidiculous Christmas Core Challenge
DAY 15🎄

Choose-Your-Challenge Monday🤨

It’s a new week, and today is all about picking the version that matches your core strength. Every move has levels, so choose the one that lets you stay controlled and honest with your form… not the one that looks the coolest🙈

We’ve got three movements, three ways to dial things up or down, and your only job is to pick the challenge that feels right for you today.

🔄3 rounds
⏱️ 30 sec Alt Leg Extensions
⏱️ 30 sec Russian Twists
⏱️ 20 sec Windshield Wipers
↔️10 sec transition between movements
⏸️ 20 sec rest between rounds

⭐ Alt Leg Extensions
Boat-hold or lean-back version, it’s your call.
Long spine, ribs down, torso stays frozen while the legs move. If your hip flexors take over, raise the legs or shorten the range.

⭐ Russian Twists
Feet down or up, weighted or unweighted.
Rotate from your ribcage, not your hands. Slow reps win here. No bouncing through the torso.

⭐ Windshield Wipers
Bent-leg (stable) or straight-leg (spicy).
Keep your opposite shoulder pinned and rotate from your trunk. Smaller range = cleaner reps.

You only have 20 seconds, so make each rep intentional.
New week, fresh challenge. The real win today is choosing the level that keeps your movement honest. Tag me when you finish so I can hype you up 🔥👏

Rhidiculous Christmas Core Challenge
DAY 14🎄
Stability Ball Sunday

Today is all about slow control and deep core engagement. The stability ball looks innocent, but it forces your core to actually do its job instead of letting your hips or low back take over. If you move too fast, you’ll feel it instantly… so don’t.

We’ve got three moves that hit your stabilizers from different angles, and we’ll cycle through them for short, focused rounds.

Ps the mods for no ball are in parenthesis. Don’t do both just do the mod if you don’t have the ball😅

⏱️ 3 rounds
30 seconds per move
10 seconds to transition
20 seconds rest between rounds

⭐ Stability Ball Stir the Pot (Plank Shoulder Taps)
Forearms on the ball, ribs down, and draw tiny circles. This should feel like a quiet, steady plank… not a wild noodle dance. Switch directions at the 15 second mark.

⭐ Stability Ball TVA Crunch (Sit-ups)
Tiny movement, big control. Think “ribs to hips” and keep the ball from taking over the motion. Slow curl, slow release. Deep core lights up here.

⭐ Stability Ball Roll-Out (Rocking RKC plank)
This is your anti-extension challenge. Let the ball roll away only as far as you can go while keeping your ribs tucked and your low back quiet. Control matters more than range here.

Stability Sundays always sneak up on you in the best way.

Tag me when you finish so I can cheer you on 👏🔥

Rhidiculous Christmas Core Challenge
DAY 13🎄

WE MADE IT PAST HALFWAY!

13 out of 25.

If you’re still here, your consistency is already paying off.

🔁2 rounds
⏰25 seconds per side for Windmill
⏰ 40 seconds total for Marches
⏰ 25 seconds per side for Cross-Body Crunch
↔️10 seconds to transition
⏸️20 seconds rest between rounds

⭐ Standing Windmill
Slow reach, long spine, ribs stacked, and rotate through your obliques. No collapsing into the hip.

⭐ Standing Marches
Tall posture. Pull the knee up from your core, not by leaning back. Think “quiet hips, quick taps.”

⭐ Standing Crossbody Crunch
Strong diagonal lines here. Let your rib-to-hip connection drive the movement, not momentum.

It’s simple, spicy, and forces you to actually own your midline while you move.

And seriously… I’m so damn proud of you for sticking with it. This might be our BEST RCCC group yet. You all are showing up like crazy and I love seeing it.

And hey, if you’ve been watching us from the sidelines or this is your first time I’ve shown up on your explore page.. it’s not too late to jump in. Thirteen days til Christmas is plenty of time for a free core advent calendar. What’s holding you back?

DAY 12🎄

One and Done Core Gauntlet

Today is all about stability. Four moves, four different ways to challenge your plank, and we hit each one once. No repeating or extra rounds.. just ONE TIME, give your best effort and you’re done.

🔁 1 Round
⏱️ 40 seconds per move
➡️15 seconds to transition

⭐ Plank Scorpions
Slow and controlled. This one is a TON of fun IMO.

⭐ Hollow Hold + Release
Think ribs down, low back anchored, long body. Hold tension, then release with control. This one teaches real core awareness.

⭐ Plank Punches
Widen your base, shift your weight, and punch without letting your hips rock. Micro-movement is okay… big sways we want to avoid.

⭐ Plank Alternating Leg Lifts
Lift from the glute, not the low back. Keep your ribs stacked and your breath steady.

It’s a sneaky burner today, but once you clear these four… you’re DONE.

Also… HAPPY FRIYAY!! What’s everyone up to this wkd? Let’s be real it’s December so I just KNOW there is a lot going on!

DAY 10🎄

🔁 2 rounds
⏸️ 30 seconds rest between rounds
⭐️ 10 Weight Raised Leg Toe Touches
⭐️ 8 Weighted Diamond Sit-ups

Weighted Wednesday is back!!!
You already know this is everyone’s favorite day every year. A little load goes a long way when you’re training the core with intention, and both of today’s moves push you to control the weight and your rib position… not just swing your arms around.

‼️LESS REPS = GIVE ME MORE CONTROL HERE‼️

⭐ Weighted Raised Leg Toe Touches
Think trunk flexion with a little anti-extension sprinkled in. Legs stay high, ribs stay down, and you’re lifting from your core… not yanking your shoulders to your toes. Small range, controlled reps👌🏼

⭐ Weighted Diamond Sit Up
Butterfly legs, weight stays straight overhead the whole time. This is pure flexion plus a stability challenge because the weight wants to pull you forward. Curl up one vertebra at a time and keep your ribs stacked as you sit tall.

Have fun with this one..Weighted Wednesday always sneaks up on you in the best way. Tag me when you finish so I can hype you up 🔥

DAY 9🎄

🔁 2 rounds
▶️ 40 seconds per move (per/side)
⏸️ 20 seconds rest between rounds
⭐️ Bird-dog Crunch
⭐️ Plank

Today we’re training slow, steady control buuuuttt have an extra lil 🌶️ (as an OPTION! you don’t have to do it)

Bird-dog crunches light up your deep core and challenge your stability, and you can level them up with a light dumbbell or ankle/wrist weight if you want a little extra challenge.

Just keep the movement clean, not sloppy.

Then we roll into a plank and focus on quiet ribs, steady breathing, and holding your hips still. Simple moves, but they hit when you do them with intention.

Tag me on your story when you finish so I can cheer you on 👏💚
