HIIT
In high-intensity interval training (HIIT), you move quickly from one cardio exercise to the next to keep your heart rate high. High-intensity resistance training focuses on high-intensity exercises done against resistance, to strengthen and build lean muscle.
TRX
TRX training is an exercise method shown to improve total body strength, stability, and cardiovascular health. This is done without traditional weight lifting, swinging kettlebells, or lifting semi-truck tires.
