Triangle pose is insanely therapeutic, as it stretches your hamstrings, your groin and your hips.
And at the same time, it's strengthening your legs and core.
When done correctly, it's also a half spinal twist.
Make sure your back foot is at 45 degrees or 11 o'clock on a clock, and not towards 9 o'clock or 6 o'clock.
Don't just hang out in your legs. Pull up through the soles of your feet and feel your kneecaps lifting and your quads firm.
Make sure your torso is long on both sides by using a block.
Glide your shoulders down your back, stack your top shoulder over your bottom shoulder, and spiral your heart to the sky. This is the part that's a half-spinal twist.
