## Before you start

Move gently and stop if you feel sharp pain, dizziness, numbness, or symptoms that feel unsafe. This routine is general fitness guidance, not medical care.

## Exercises

### 1. Dumbbell Situp

3 sets · 12 reps · 40s rest

A weighted sit-up. Hold the bell close so the load stays over the hips.

#### Steps
- Lie on your back with knees bent at 90 degrees and feet flat on the floor or anchored under a pad.
- Hold a dumbbell against your chest with both hands, hugging it close to your sternum.
- Brace your core and tuck your chin slightly toward your chest before starting the rep.
- Sit all the way up by curling your torso forward until your elbows pass over your knees.
- Pause briefly at the top, keeping the dumbbell tight against your chest the whole time.
- Lower yourself back down slowly under control until your shoulder blades touch the floor.

#### Cues
- Weight at the chest.
- Roll up slowly.
- Feet stay down.

#### Common mistakes
- Yanking the head and neck forward to start the rep, which strains the neck instead of the abs.
- Dropping back down quickly and bouncing off the floor instead of controlling the lowering phase.
- Holding the dumbbell out in front of the chest, which loads the shoulders instead of the abs.
- Hooking the feet too aggressively under a pad, which lets the hip flexors do most of the work.

### 2. Hanging Knee Raises

3 sets · 10 reps · 40s rest

Hanging removes the floor entirely, so the lower core has to do all the lifting.

#### Steps
- Hang from a pull-up bar with hands shoulder-width apart and arms fully extended overhead.
- Engage your shoulders by pulling them slightly down and back to keep your body stable.
- Bend your knees and pull them up toward your chest by curling your hips under, not just lifting the legs.
- Squeeze your abs hard at the top with your knees pulled high and your pelvis tilted up.
- Lower your legs slowly back down over 2 to 3 seconds until you reach a dead hang again.
- Repeat without swinging, letting the bar still completely between reps if needed.

#### Cues
- Hang tall.
- Curl the knees up.
- Stop the swing.

#### Common mistakes
- Swinging the body for momentum, which removes ab engagement and turns the rep into a leg swing.
- Lifting the knees with the hip flexors only, never tilting the pelvis up to load the abs.
- Dropping the legs fast at the bottom, which trains the descent poorly and adds shoulder strain.
- Hanging completely loose at the shoulders, which stresses the joints and reduces core stability.

### 3. Band Wood Chopper

3 sets · 12 reps · 35s rest · both sides

Rotation under tension. Let the ribs lead and keep the hips relatively still.

#### Steps
- Anchor a band at shoulder height or slightly above on your left side and stand perpendicular to the anchor.
- Grip the handle with both hands and step away until the band has tension across your body.
- Pull the handle down and across your body toward your right hip, rotating through the torso.
- Pivot your left foot as you rotate, fully turning the trunk to load the obliques explosively.
- Slowly return to the starting position over 2 to 3 seconds, fighting the band's pull the whole way.
- Complete 8 to 12 reps per side, then switch the anchor and work the opposite direction.

#### Cues
- Turn from the ribs.
- Arms stay long.
- Control the return.

#### Common mistakes
- Pulling with the arms instead of rotating through the trunk — turns the move into a one-arm row.
- Skipping the foot pivot, which limits the rotation range and stresses the lower back.
- Going too heavy and breaking form — the chop should look athletic and controlled, not rushed.
- Forgetting to work both sides equally, leaving the trunk imbalanced for rotational sport.

### 4. Kettlebell Windmill

3 sets · 6 reps · 45s rest · both sides

A demanding shoulder and waist movement. Start with no weight until the path feels natural.

#### Steps
- Stand with feet wider than shoulder width and press a kettlebell straight overhead with one arm.
- Turn your front foot out about 45 degrees and lock your eyes on the kettlebell overhead.
- Push your hips toward the side of the locked-out arm while keeping the bell straight up.
- Hinge sideways and reach the lower hand down the inside of the front leg toward the floor.
- Pause at the deepest position with the bell stacked over the shoulder and the back leg straight.
- Reverse the hinge by driving the hips back under the kettlebell to return to standing.

#### Cues
- Eyes on the bell.
- Hips shift back.
- Slow and short.

#### Common mistakes
- Letting the overhead arm drift forward or back instead of staying stacked over the shoulder.
- Bending the knee of the back leg, which collapses the stretch through the obliques and hamstrings.
- Loading too heavy too soon, which compromises shoulder stability under the bell.
- Looking forward instead of tracking the kettlebell, which often causes the arm to drift.

### 5. Dumbbell Spinal Jefferson Curl

2 sets · 6 reps · 40s rest

Ends by moving the spine segment by segment under a very light load.

#### Steps
- Stand on a box or bench with feet hip-width apart and a light dumbbell held with both hands in front.
- Stand tall, brace lightly, and tuck your chin toward your chest before starting the curl.
- Begin rolling your spine down one segment at a time, starting from the top of the neck.
- Continue rolling down through the upper back, mid-back, and lower back until the dumbbell drops below the box.
- Hold briefly at the bottom with the legs straight and the dumbbell hanging freely below your feet.
- Roll back up the same way you came down, restacking the spine one segment at a time until standing tall.

#### Cues
- Roll down slowly.
- Knees soft.
- Light weight.

#### Common mistakes
- Going too heavy too soon, which forces the lower back to bear more load than it's ready for.
- Bending the knees during the descent, which removes the hamstring stretch and changes the drill.
- Dropping straight down at the hips instead of rolling segment by segment through the spine.
- Standing back up by hinging at the hips first, which skips the segmental restack of the spine.
