Why Train with an Alpha Strong Sand Vest

Thy Sand Vest was designed by Alpha Strong to improve your speed, mobility, agility, endurance, and general athleticism. You will be able to perform more explosive movements at higher speeds and improve your overall body strength and stamina after training with this tool. Translation: Get after it! The Vest will enhance any workout by providing resistance from the added weight at your core. Walking, jogging, running, bodyweight exercise and sport specific training (hockey, basketball, baseball, football or training for a Tough Mudder) are all more challenging as your muscles, bones, neuromuscular and cardiovascular systems have to work harder than normal with the vests shifting weight. So post workout, when you play for fun or for life without the vest on you will feel truly Alpha Strong.

Our vest is built for comfort and optimum function-ability to allow you to move freely while performing sport specific, explosive moves, or whatever moves you to be strong and reach your personal goals.

Added Alpha Features include:

  • Sand channels constructed to allow ideal sand shifting, to simulate your natural body movement & protect shoulders and spine.
  • Bungee cord closure ensures vest stays in place and snug
  • Quick release attachment hardware for easy removal to perform sprints with or without vest
  • Spacer mesh against your body for breathability and cushion
  • Reflective safety material for late running, and outside night workouts
  • Backpack foam in shoulder straps for extra comfort
