Join Jenna for an energizing 30-minute cardio blast that will get your heart pumping and body moving. This workout features three dynamic blocks: a bodyweight cardio block with skaters, high knee sprints, squat jumps, and mountain climbers; a weighted power block with dumbbell thrusters and plank variations; and a core-focused block with burpees and V-ups. Finish strong with an agility ladder combining jump lunges and jumping jacks. Equipment needed: Light dumbbells (Jenna uses 15 lbs), yoga mat (optional: yoga block or pillow for stretching)
