Push yourself to the limit with this 30-minute boxing, running and conditioning class. Each block is 6 minutes and there are 3 in total – plus you can do this workout at home or in the gym if you like. Block 1 is shadow boxing with burpees and scissors. You’ll be doing prisoner high knees and squats in block 2 if you’re at home, or running on the treadmill in the gym. And block 3 is plank forward reaches and explosive jacks if you’re at home, or sandbell pull throughs and slams in the gym.
