I approach my exercise from many different angles, in the hope of creating a dynamically balanced practice. My passion is bellydance and dance fusion, and I study many dances including notably capoeira, which I think adds a lot to my strength and agility. I feel like my legs are very strong, and indeed they are quite muscular, and I am able to do certain level changes and holds in dance that require a good deal of strength. I've been doing so much dancing, yoga, and running lately that I haven't had much of an opportunity to go into the gym and work with weights. But I do enjoy the particular balancing quality that it has on muscle groups. I worked on the thighs today and I remembered an enigmatic thing that has long puzzled me: with these great strong thighs, I put on 45lbs for extension and it's killing me. I can barely do it, the burn is crazy (in the belly of the muscle, not the joints). I take it down to 30, almost the lowest setting. It's still really intense, but I can do it. Pausing at the top. The hamstrings are cool with 45lbs, I'm feelin it but it's all good. And the adductors and abductors are just engaged at 55lbs. So I'm just wondering, with all their plumage, why do you suppose there is this hidden weakness in my quads? Could it be fatigue or imbalance because I use them so much in dance? Or are they just not as strong as they look?
