The task asks you to demonstrate understanding of Static Stretches versus Dynamic Stretches by listing 5 examples of each and, for extra credit, describing any sub-set groups within the given stretch grid. I will first outline how to differentiate the two categories, then provide concrete examples for each, and finally touch on potential subgroups you could describe for extra credit.

Understanding the categories:
- Static stretches: these involve holding a muscle in a fixed end-range position for a period of time (commonly 15–60 seconds) to improve flexibility and promote gradual lengthening. They are typically performed after activity or as a separate flexibility session and are not designed to produce rapid, sport-specific movement.
- Dynamic stretches: these involve moving parts of your body through a full range of motion with control, usually to prepare the body for activity by increasing blood flow, activating muscles, and rehearsing movement patterns. They are performed in a controlled, functional manner and are generally done in sets of repetitions rather than held poses.

Now, 5 Static Stretches (examples and rationale):
1) Standing Hamstring Stretch (RDL or straight-leg reach with a hold): Hold your forward fold or hamstring stretch position, keeping the knee slightly bent or straight, and hold for 20–40 seconds. Rationale: targets the hamstrings and posterior chain while teaching length in a fixed position.
2) Chest Stretch against a wall: Place forearm on a wall and gently rotate the torso away to feel a stretch across the chest and front shoulder. Hold 20–40 seconds. Rationale: stretches pectoral muscles and anterior shoulder in a static stance.
3) Overhead Lat/Side Bend Stretch: Reach one arm overhead and lean slightly to the opposite side while keeping shoulders relaxed; hold for 20–40 seconds. Rationale: lengthens latissimus dorsi and intercostals in a stationary posture.
4) Hip Flexor Stretch (kneeling lunge with pelvis square): Kneel on one knee, gently press hips forward while keeping torso upright, hold 20–40 seconds. Rationale: lengthens the hip flexors and anterior hip structures in a fixed position.
5) Quadriceps Stretch (standing quad stretch with balance support): Stand on one leg, pull the heel toward the glute, keep knees aligned, and hold for 20–40 seconds. Rationale: stretches the rectus femoris and surrounding quadriceps without dynamic movement.

5 Dynamic Stretches (examples and rationale):
1) Leg Swings (forward and backward): Stand on a stable support and swing each leg in a controlled arc, 10–15 reps per leg. Rationale: actively increases hip flexor and hamstring mobility with momentum in a safe range.
2) Arm Circles (small to large, forward and backward): Perform 10–15 circles each direction. Rationale: warms up shoulder girdle and increases range of motion actively rather than in a static hold.
3) Walking Lunges with Torso Twist: Step into a lunge, rotate the torso toward the lead leg, and return to standing; alternate sides for 8–12 reps per side. Rationale: primes hips, thoracic rotation, and glute activation through dynamic movement.
4) Inchworm to Plank: From standing, hinge to place hands on the floor, walk hands forward to a high plank, then walk feet to hands; repeat for 6–10 reps. Rationale: activates posterior chain, shoulders, and core through dynamic lengthening and contraction.
5) Hip Circles with Step-Through: Stand with feet hip-width apart, perform controlled hip circles and then step through into a light lunge, alternating sides for 8–12 reps. Rationale: mobilizes hip joints and integrates dynamic movement patterns.

Optional sub-set groups you could describe for extra credit (as seen in the stretch grid):
- Traditional Static Stretching: classic holds like the quad stretch, calf stretch, or hamstring stretch held for a period of time.
- Assisted (Passive) Stretching: a partner or gravity assists the stretch to deeper end-range positions.
- Active Stretching (Reciprocal Inhibition): using the agonist muscle to actively lengthen the antagonist without external force.
- PNF Stretching (Proprioceptive Neuromuscular Facilitation): involves a sequence of contraction and relaxation to improve range of motion, often requiring a trainer or partner.
- Dynamic vs Ballistic distinctions: Dynamic involves controlled movement through range (as listed above), while ballistic would use bouncing or jerky movements, which are generally not recommended for static stretch training.

When presenting these in a chart or grid, you could label each item with its category (Static or Dynamic), specify the primary muscle groups targeted, typical hold times for static stretches, and the number of repetitions or reps for dynamic movements. This demonstrates clear understanding of both the difference between static and dynamic stretching and the nuances within the stretch grid.
