Jessie Salas on Instagram: "What if you could get all the lactic-acid training benefits — without heavy loads, joint stress, or brutal fatigue? That’s the power of KAATSU: light weights, controlled pressure, and huge metabolic payoff. You trigger the same adaptation signals you’d get from high-intensity lifting, but with a fraction of the mechanical stress. ⚡️⚡️⚡️⚡️KAATSU restricts venous return just enough to pool blood, spike lactate, and create metabolic stress, all while keeping loads light
