Regarding the side to side lunges in the warmup, from what I've gathered, strength and flexibility combine to create mobility. Which should I be focusing on first? As in...I can get my legs into the appropriate position, but I don't have the strength to maintain an upright stance, so I lean forward (at the hips, keeping my back straight), and rest my hands on the ground to get a deep stretch. OR...I can keep my hips higher and feel the muscles in my thighs engaging, but there's absolutely ZERO stretch for me in this position. I tend to have pretty high flexibility, so my instincts tell me I should focus on getting my strength up to that level first and not worry about getting deep, but I'd like confirmation. (I DEFINITELY don't have the strength slide across the middle in a low stance).
