This is primarily an alignment pose which is practiced before a number of seated asanas as a foundational pose to start from. Dandasana (Daṇḍāsana) is usually followed by some kind of a forward bend, but not always so.
Leg Strengthening
Side Reclining Leg Lift (Anantasana)
Anantasana tones and strengthens the abdominal muscles, sides of the torso, spine, thighs, hamstrings, glutes, and calves. It improves digestion and boosts blood circulation in the lower regions of the body.
Side Plank Pose (Vasisthasana)
Vasisthasana tones and strengthens the wrists, biceps, triceps, forearms, shoulders, spine, and core muscles. It also engages the glutes, quads, calf muscles, and hamstrings, improving the strength in the lower body.
Shoulder Pressing Pose (Bhujapidasana)
This asana strengthens the arms, shoulders, biceps, triceps, wrists, spine, glutes, thighs, hamstrings, and the abdominal area. It instills in the system, a strong sense of balance, coordination, and willpower.
Scale Pose (Tolasana)
This asana strengthens the forearms, wrists, biceps, triceps, and shoulders. It builds upper body strength and develops the core muscles. Just like Padmasana, this pose works on the knees, thighs, hamstrings, and calves.
