Hub Cold Start (warm up first!)

Metabolic Conditioning — HIIT

~25 min cardio with one light dumbbell. Non-stop movement, full-body conditioning. Counts as HIIT.
Grab ONE dumbbell, 8-15 lb. This isn't a strength workout — the weight adds just enough resistance to turn bodyweight cardio into full-body conditioning. If you don't have a light DB, a filled water bottle or medicine ball works. Keep moving — minimal rest between exercises, 20-30 second break between sets.

Set 1 — Upper Body + Cardio ~6 min

1
Press Jacks
30s x 2 rounds
Jumping jacks while pressing the dumbbell overhead with each jack. Full body: legs + shoulders + core stabilization. The overhead press under cardio demand trains shoulder endurance while keeping your heart rate climbing.
  1. Hold the DB in both hands at chest height.
  2. Jump feet out (standard jack) while pressing the DB overhead.
  3. Jump feet in, bring DB back to chest. That's one rep.
  4. Keep the press controlled — don't just fling it. The DB should reach full extension at the top of each jack.
Key cue: "Press at the top, chest at the bottom. Controlled overhead, not a fling." If your shoulders fatigue early, use a lighter weight — this is cardio, not strength.
Should feel: Shoulders burning by round 2, elevated heart rate. Full-body rhythm.
2
Atlas Twists
30s x 2 rounds
Rotational power + hip hinge + thoracic rotation. You're "picking up a book" from the floor and "putting it on a shelf" — a diagonal pattern that loads the entire posterior chain through rotation. Great for thoracic mobility under light load.
  1. Hold the DB in both hands. Feet shoulder-width apart.
  2. Bend and twist to "pick up a book" from the floor on your LEFT side. Hinge at the hips, don't just round your back.
  3. Twist and reach the DB up HIGH to your RIGHT side — like putting it on a top shelf. Full hip extension + thoracic rotation.
  4. Alternate sides each rep. Continuous flow — down-left, up-right, down-right, up-left.
Key cue: "Floor to shelf, diagonal path, hinge don't round." The power comes from the hip drive, not your arms.
Should feel: Deep thoracic rotation, mild hamstring stretch at the bottom, core engagement throughout.
3
March & Reach
30s x 2 rounds
Dynamic hamstring stretch + overhead shoulder endurance. Hold the DB overhead and do stiff-leg marches — kick one leg up while reaching the DB down toward your toe. "Stiff zombie" style. The overhead hold taxes your shoulders isometrically while the marching stretches hamstrings dynamically.
  1. Hold the DB overhead in both hands, arms extended.
  2. Kick your RIGHT leg straight up (keep it as straight as possible) while reaching the DB down toward your right toe.
  3. Return to standing tall, DB overhead. Kick LEFT leg, reach to left toe.
  4. Alternate continuously. Keep your standing leg straight too — full zombie march.
Key cue: "Stiff zombie — straight legs, DB meets the toe." Don't round your back to reach. Let the hamstring stretch happen naturally. Height improves as you warm up.
Should feel: Hamstring stretch on the kicking leg, shoulder burn from the overhead hold, core bracing throughout.

Set 2 — Lower Body Focus ~6 min

4
Traveling Tire Twist
30s x 2 rounds
Core rotation + cardio. Imagine high-stepping through tires while rotating a dumbbell from hip to hip. The high knees drive your heart rate while the rotational twist loads your obliques and transverse abdominis under movement.
  1. Hold the DB at hip height in both hands.
  2. High-knee forward (3-4 steps), twisting the DB from your LEFT hip to your RIGHT hip with each step.
  3. High-knee backward (3-4 steps), continuing the hip-to-hip twist.
  4. Continuous — forward and back, twisting the whole time. Drive those knees up.
Key cue: "High knees, hip to hip, travel forward and back." The twist should come from your torso, not just your arms swinging.
Should feel: Heart rate spiking from the high knees, obliques engaged from the rotation.
5
Frog Squat Reach
30s x 2 rounds
Full hip extension + overhead reach. Wide squat down, DB touches the floor, then explode up reaching the DB overhead. Combines deep squat mobility with explosive power. The wide stance reduces ankle dorsiflexion demand.
  1. Wide stance, toes pointed slightly out. Hold DB in both hands.
  2. Squat deep — touch the DB to the floor between your feet. Chest stays up.
  3. Explode up, reaching the DB overhead. Full hip and knee extension at the top.
  4. Flow back down immediately. Continuous reps for 30 seconds.
Key cue: "Floor to ceiling, explode up, soft landing." Use heel elevation (a plate or folded towel) if ankle dorsiflexion limits your squat depth.
Should feel: Quads and glutes driving the explosion, shoulders catching the DB overhead. Full-body integration.
Wrong if: Heels lifting off the floor, back rounding at the bottom, or knees caving inward. Widen your stance or elevate heels.
6
Arc Press Lunge
30s x 2 rounds
Multi-plane loading. Alternating lunges with an arcing DB press — as you lunge right, arc the DB from left hip to overhead right. This loads the body in the sagittal plane (lunge) and transverse/frontal plane (arc press) simultaneously. Functional movement at its best.
  1. Hold the DB in both hands at your LEFT hip.
  2. Step RIGHT foot back into a reverse lunge. As you lunge, arc the DB from your left hip up and over to your RIGHT side overhead.
  3. Push back to standing, bringing the DB back to starting position.
  4. Switch: DB starts at RIGHT hip, lunge LEFT foot back, arc the DB to your LEFT side overhead.
  5. Alternate continuously. The arc should be smooth, not jerky.
Key cue: "Lunge and arc — opposite hip to overhead. Smooth rainbow path." The DB traces a rainbow arc as you lunge.
Should feel: Quads and glutes from the lunge, shoulders and core from the arc. Coordination challenge.

Set 3 — Balance + Power ~6 min

7
Hop Overs
30s x 2 rounds
Agility + calf conditioning. Quick lateral jumps over a towel (or imaginary line). Light and bouncy — this is about fast feet and elastic rebound, not height. Trains the reactive strength component that heavy lifting misses.
  1. Place a towel or small object on the floor. Stand to one side of it.
  2. Jump laterally over it, landing softly on both feet. Immediately jump back.
  3. Quick feet — think speed, not height. Stay on the balls of your feet.
  4. 30 seconds of continuous side-to-side hops. No DB needed for this one.
Key cue: "Light and bouncy, quick feet, soft landings." If your calves burn, you're doing it right. If your knees hurt, jump lower.
Should feel: Calves and ankles working, elevated heart rate, light and reactive.
8
Balance Pull
30s x 2 rounds (switch legs each round)
Single-leg balance + oblique crunch. Standing on one leg, you pull the DB-side knee up to meet the DB at your chest. The balance challenge fires your ankle stabilizers and glute med while the crunch hits obliques. Switch legs each round.
  1. Stand on your LEFT leg. Hold the DB at your chest with both hands.
  2. Lift your RIGHT knee up toward the DB. Crunch your torso slightly toward the knee — like a standing oblique crunch.
  3. Lower the leg back down (don't touch the floor if you can). Repeat for 30 seconds.
  4. Round 2: switch to standing on RIGHT leg, crunching LEFT knee up.
Key cue: "Knee to DB, slight crunch, don't touch down." Focus on the standing leg — that's doing most of the work. If balance is shaky, lightly tap the toe between reps.
Should feel: Standing-leg glute med burning, obliques engaging on the crunch, ankle stabilizers firing.
9
Twist & Pivot
30s x 2 rounds
Rotational power + hip mobility. Feet shoulder-width, DB at chest, you rotate your ENTIRE body 90 degrees — pivoting on your feet. This trains rotational power through the hips and thoracic spine together, not in isolation. Think of a boxer's turning punch.
  1. Stand with feet shoulder-width apart. Hold DB at chest height.
  2. Pivot on your feet and rotate your entire body 90 degrees to the RIGHT. Your feet, hips, torso, and head all rotate together.
  3. Pivot back to center, then rotate 90 degrees to the LEFT.
  4. Keep your head facing the direction of rotation — don't keep your head straight while your body turns.
  5. Continuous pivoting, 30 seconds. The DB stays at chest height throughout.
Key cue: "Whole body pivots — feet, hips, torso, head. 90 degrees each way." The power comes from the ground up through hip rotation. Not an arm twist.
Should feel: Hips and feet driving the rotation, core bracing to control the DB, smooth pivoting rhythm.

Set 4 + Burnout ~6 min

10
Side Reach Jumps
30s x 2 rounds
Lateral power + full-body integration. Squat and reach the DB toward the floor on one side, then explode up and reach it high to the opposite side. This is a diagonal power pattern — like a lateral version of the Frog Squat Reach.
  1. Hold the DB in both hands. Feet shoulder-width apart.
  2. Squat and reach the DB toward the floor on your RIGHT side.
  3. Explode up, jumping slightly, and reach the DB high to your LEFT side overhead.
  4. Land softly, immediately squat and reach to the LEFT side.
  5. Explode up and reach high to the RIGHT. Alternate continuously.
Key cue: "Low right, high left. Low left, high right. Diagonal explosion." The jump doesn't need to be huge — even a small hop adds the explosive element.
Should feel: Quads and glutes driving, obliques controlling the lateral reach, heart rate peaking.
11
Crescent Chair
30s x 2 rounds
P90X3 yoga meets cardio. Alternate between crescent lunge and chair pose while holding the DB at your chest. The transitions challenge balance, hip flexor flexibility, and quad endurance. The held positions add an isometric component to the cardio flow.
  1. Hold the DB at your chest. Step your RIGHT foot back into a crescent lunge (back knee hovers above the floor, arms could extend up if no DB).
  2. Hold crescent for 3 deep breaths. Feel the hip flexor stretch on the back leg.
  3. Step RIGHT foot forward into chair pose — feet together, squat with weight in heels, torso slightly forward.
  4. Hold chair for 3 deep breaths. Quads burning.
  5. Step LEFT foot back into crescent lunge. Hold 3 breaths. Step forward to chair. Repeat.
Key cue: "Crescent, breathe 3. Chair, breathe 3. Alternate legs back." The slow pace is intentional — catch your breath while your legs work isometrically.
Should feel: Quads on fire in chair, hip flexor stretch in crescent. Heart rate recovering slightly from the slower pace.
12
Globe Squatters
30s x 2 rounds + 60s burnout
The finisher. Squat, sweep the DB in a big circle around your head, hop at the top. Continuous movement that hits quads, shoulders, core, and cardio all at once. After 2 normal rounds, you do a 60-second burnout at maximum pace. Leave nothing in the tank.
  1. Hold the DB in both hands. Squat down.
  2. As you stand up, sweep the DB in a big circle (globe) around your head — right side, over the top, left side, back to center.
  3. Add a small hop at the top of the movement.
  4. Squat back down, sweep the globe the other direction. Continuous.
  5. Rounds 1-2: 30 seconds each, normal pace.
  6. BURNOUT: 60 seconds straight at MAXIMUM pace. This is the last exercise. Empty the tank. Go until you can't.
Key cue: "Squat, globe, hop. Squat, globe, hop. Burnout = max effort, 60 seconds, don't stop." The globe should be a smooth circle, not a jerky path.
Should feel: Everything. Quads, shoulders, core, lungs. By the burnout you should be gasping. That's the point.
