Well if it’s any weight to the on going conversation of added strength concerning sports. I’ll agree with the other guys that it’s generally beneficial.
I used to be on the swim team all throughout highschool. I was about sub 115lbs. I would ALWAYS come in third place. No matter how I specified my training, or what have you. I remember clear as day the chick who would always come in first. I can’t remember her face, but she had what I will confidently describe as the thickest, most dense pair of legs I’ve ever seen in real life. And I would always see her in the weight room on Monday’s and Wednesday’s. She wasn’t really top heavy, but her legs…her…legs. She was short like myself, but I really don’t think that mattered since the chick who always came in second topped out at 6 foot 2.
Fast forward to me now I’m hovering around 189-190, and I can easily see myself beating my old highschool times if I decided to specifically swim and train for that. Strong legs are awesome for chopping through water.
I’ve also seen some well built/dense lady gymnasts with freaking tree trunks for legs, and they kick ass on the trampoline, and floor routines where they’re sticking double front and black flips, along with a plethora of other gymnastics tricks.
