It's a lot easier than some people might think. I thought we had to be super flexible going into that class to be successful but I've learned that these poses are made to improve flexibility even if you don't have any at all. I seriously suggest taking a yoga class whether it's from a gym, school or a yoga studio...I'm not kidding when I say it's probably the best thing since Nutella! (we all know how much I love Nutella.)
Here are a few of my favorite poses:
Benefits: Strengthens arms, shoulders, quads; stretches shoulders, chest, hamstrings, calves; keeps spine flexible
Helps: Fatigue, mental alertness
Any of the Warrior poses- I, II, III or Reversed Warrior
Benefits: Strengthens core, legs, ankles; lengthens spine
Helps: Poor posture, weak knees, endurance
Side Plank:
Benefits: Strengthens wrist, abs, legs
Helps: A scattered mind
Half Moon:
Benefits: Strengthens back, glutes, legs; keeps spine flexible
Helps: Insecurity
Crow
Benefits: Strengthens arms, shoulders, chest, abs, upper back
Helps: Poor balance, a scattered mind
