@south.signal: Could you finish this workout—and then do it again tomorrow? That is the kind of fitness I need for Greenland. A polar expedition is not one maximum-effort day followed by recovery. It is hours of repetitive movement, pulling a sled, lifting skis and boots, managing equipment, setting camp, sleeping, and then waking up to repeat the entire process. Two of the stranger tools I sometimes use are ankle weights and an “altitude” mask. The ankle weights are there to make every leg movement slightly more expensive. They add resistance at the end of the limb, so my hip flexors and the muscles responsible for repeatedly lifting and moving my legs have to work harder. They are not a perfect simulation of skiing, and I don’t use them for every workout, but they give me a simple way to overload a movement I will repeat thousands of times each day. The mask needs an important disclaimer: it does not magically recreate training at altitude. It does not reduce the percentage of oxygen in the air or create the same adaptations as living at elevation. What it does is restrict airflow, adding resistance to breathing and making me stay controlled when the effort becomes uncomfortable. Neither tool is magic, and neither replaces normal strength and aerobic training. They simply let me add very specific stress to certain sessions. The goal is not to become exceptionally good at one brutal workout. It is to build a body that can work efficiently, recover quickly, and return to the effort tomorrow—even when tomorrow is day 20... And I've slept poorly... and the sled still needs to move... For ten hours. 😂 #expedition #training #Fitness #endurance #endurancetraining
