For me, it was a CrossFit workout called “Murph”. It’s a combination of a one-mile run, 100 pull-ups, 200 push-ups, 300 air squats, and another one-mile run. It took me over an hour to complete and I was completely exhausted afterwards.
I tried a boxing class once and it was definitely the hardest workout I’ve ever done. The combination of punching and footwork was really challenging, and I was completely worn out by the end of the class.
I used to do competitive rowing in college, and the training was grueling. We would spend hours on the water every day and also do weightlifting and cardio workouts on top of that. It was definitely a full-time commitment.
I participated in a Spartan Race once, and it was definitely the hardest workout I’ve ever done. The obstacles were incredibly challenging and the course was very hilly, so it was a real test of strength and endurance.
