## 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. Forward Lunge

1 set · 8 reps · 20s rest · both sides

Step forward, pause a moment, then push back to standing. Hold a wall for balance if you need it.

#### Steps
- Stand tall with your feet hip-width apart, hands on your hips or relaxed at your sides.
- Step forward with one leg into a long stride, landing softly on the heel and rolling onto the foot.
- Lower your back knee straight down toward the floor until both knees form roughly 90-degree angles.
- Keep your torso upright with your front knee tracking over your front foot at the bottom.
- Push through the front heel to drive yourself back up and step the front foot back to the start.
- Alternate legs each rep or finish all reps on one side before switching, depending on the program.

#### Cues
- Step and settle.
- Front knee over foot.
- Push back tall.

#### Common mistakes
- Letting the front knee cave inward, which strains the knee and shifts work away from the glutes.
- Taking too short a step forward, forcing the front knee to push way past the toes and stressing the joint.
- Leaning the torso forward over the front leg, which loads the lower back instead of the legs.
- Slamming the back knee into the floor instead of stopping just above it under control.

### 2. Mountain Climber

1 set · 16 reps · 25s rest

Drive the knees without letting the hips bounce. Slow the feet down before the plank position breaks.

#### Steps
- Set up in a high-plank position with your hands directly under your shoulders and arms locked out.
- Brace your core hard and squeeze your glutes to keep your hips level with your shoulders.
- Drive your right knee toward your chest, keeping the foot off the floor at the front of the motion.
- Snap the right leg back as you drive the left knee forward in a smooth, alternating rhythm.
- Keep the hips low and the shoulders stacked over the wrists the entire set.
- Continue for 20 to 40 seconds at a controlled pace, prioritizing form over raw speed.

#### Cues
- Hips stay low.
- Quick feet.
- Shoulders over hands.

#### Common mistakes
- Letting the hips bounce up and down, which removes the core demand and breaks the plank shape.
- Sagging the lower back as the legs drive, which strains the spine instead of loading the core.
- Putting the hands too far in front of the shoulders, which collapses the plank and stresses the wrists.
- Going too fast and losing range of motion, with knees barely moving instead of driving toward the chest.

### 3. Hand Plank

1 set · 20s hold · 20s rest

Hold a high plank with straight arms. Keep the body long, breathe steadily, and lower the knees if the position feels too intense.

#### Steps
- Start on all fours with your hands flat on the floor directly under your shoulders.
- Step both feet back one at a time until your legs are straight and your body is in a long line.
- Press the floor away to spread your shoulder blades and keep a slight rounding through the upper back.
- Squeeze your glutes and brace your abs to stop your hips from sagging or piking up.
- Hold the position with steady breathing, eyes looking down between your hands to keep a neutral neck.
- Lower your knees back to the floor with control after the target time and rest before the next set.

#### Cues
- Press the floor away.
- Body stays long.
- Breathe steadily.

#### Common mistakes
- Letting the hips sag toward the floor, which loads the lower back instead of the abs.
- Piking the hips up high, which turns the plank into a partial downward dog and removes the core challenge.
- Letting the head drop or crane forward, which strains the neck and breaks the body's straight line.
- Locking the elbows and sinking into the shoulders instead of pressing the floor away.
