In today's training it became clear to me that stuff I worked at is improving but at the same time some things are definitely requiring my attention - for example - Stride length. From now on I will implement more exercises for stride length improvement. Generally, there is so much work to do but that's what makes me excited 🙌 #testarossadiaries #explosivetraining #100m #sprinting #acceleration...

    @alberthammer1059 4 дня назад

    Congratulations on your videos, you're truly persistent and also very beautiful. If I could offer some advice, when you run, you should adopt a different posture. You have a stance that's too rigid and doesn't flow with your running. If you'd like to start with something important, always keep a longer stride. Don't get used to a stride that's too short, as this prevents your muscles from fully extending, and they 'get used to it poorly,' not developing as they should. When you step down with your foot, try working on distance, always aiming a bit further. You need to work on power with the thrust, but in general, focus on lengthening your stride...

    • @Testarossadiaries
      @Testarossadiaries 3 дня назад

      Thank you for a great advice 🙏 Yes stride length apparently is my biggest weakness and requires more attention. Different variations of jumping exercises, bounding, resistance bands, longer distance lower intensity runs etc. That's what I'm doing right now. If you have more advices, I will gladly take it from you 🙌

      @@Testarossadiaries Stretching and lengthening exercises, running posture, but above all, the use of all your muscles during running and stride. To lengthen your stride, it's important to mark reference points daily... with the videos you're making, it's an excellent method-well done! Then, compare them. Here are some exercises ;) you can do to improve your stride length: 1) High Knees: This exercise boosts your knee lift and strengthens hip flexors, contributing to a longer stride. 2) Bounding: Exaggerated running steps focusing on power and distance help improve explosive strength and stride length. 3) Lunges: Forward and walking lunges strengthen your quads, hamstrings, and glutes, enhancing overall running strength. 4) Leg Swings: Dynamic stretching of the hip flexors and hamstrings increases flexibility for a longer stride. 5) A-Skips and B-Skips: Drills that improve coordination, form, and activate key muscles used in running. 6) Plyometric Exercises: Activities like jump squats and box jumps build explosive power in your legs. 7) Ankle Mobility Exercises: Improve flexibility in your ankles to allow a better range of motion during strides. 8) Resistance Band Work: Using bands to strengthen smaller stabilizing muscles can improve overall stride efficiency. Incorporate these exercises into your training routine to make the most of your stride length improvements. Keep up the good work with your videos-they're a great way to track your progress!

    Diana, I feel that watching you sprint, it looks as though you’re under striding. Many people struggle with over striding. Either scenario will slow a sprinter down and not allow them to achieve full speed. I don’t know how tall you are, but I would have a partner help you measure your stride length during full speed to see if it’s within what should be optimal for you. I know it will improve as you get stronger and more conditioned. Just a suggestion.😊

    • @Testarossadiaries

    • @Testarossadiaries

      Definitely worth to start again! If we think more about it sprints help to improve vital paterns like explosiveness, velocity, mobility, it strengthens body musculature and tendon/ligaments. To me it's the best prevention against aging. I love lifting weights, martial arts and other activities as well, however sprinting can be also the most budget friendly at least for amateurs 🙌

      Thank you for subscription I as well want to see my own progress haha. According to training plan I already started running longer sprints for endurance and tempo control. Some days it's all I do, some days along with explosive training, I run at least one 300-400 meters. It really helps
