Maybe you could incorporate ruck training into your workouts. A ruck is a backpack filled with either bricks or a sandbag. The weight depends on your fitness level, but you could start with 20-30 lbs. and then as you get stronger add more weight. Rucking will increase your stamina, strength and mental level. Especially your lower body which you need for downhill skiing or recreation skiing. Add some hill climbing, a variety of bodyweight exercises (squats, lunges, jumps, pushups, etc.) and even some running (start with small distances and then increase the mileage). Long walks with a ruck will improve your lower body’s muscular endurance as well as your upper body strength. Climbing or descending hills, stairs and other uneven surfaces will also improve your lower body strength and endurance. You could also wear a ruck when you push or drag other equipment such tires, ropes, chains, weight sleights, kettlebells, etc. I use this type of training not only for myself, but also with my clients and they have seen tremendous results in many areas. Rucking can be combined with other conventional and functional training to increase the effectiveness of your training regimen. It’s just another option for you to consider when designing a fitness plan for your training.
