Strength and Conditioning

Strength and Condition classes combines weightlifting, sprinting, and gymnastics with MMA training movements such as heavy bag training, ground & pound dummy training.  says that proficiency is required in each of ten fitness domains: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination, and accuracy are ten fitness domains in which Sixel's Fight Club's Strength and Condition program emphasizes. It defines fitness as increased work capacity across all these domains and says its program achieves this by provoking neurological and hormonal adaptations across all metabolic pathways. Over time students experience weight loss, increased flexibility, and an overall higher level of fitness.


 Jiu-Jitsu and Judo emphasizes taking an opponent to the ground and utilizing ground fighting techniques and submission holds involving joint-locks and choke holds also found in numerous other arts with or without ground fighting emphasis. The premise is that most of the advantage of a larger, stronger opponent comes from superior reach and more powerful strikes, both of which are somewhat negated when grappling on the ground.
