Yoga terms: Hasta Tadasana
This is a good way to activate and engage the muscles of the back and spine to warm them up for a forward bend.
Feet parallel 3-6 inches apart. knees rotated inward slightly. Hamstrings and glutes engaged. Lower back relaxed. Chest out with shoulder blades drawn together and arms straight. Arms straight as possible for arching variation but not required.
Don’t over do the arch, just stretch and activate.
