Now when the winter time really has kicked in here in Sweden, it's a perfect time to hit the gym and prepare my body for the upcoming season. I usually do five sessions at the gym per week. Two are running sessions when I run about 7 km, in the other sessions I focus on my strengh.
i also work out a lot for windsurfing.
i think you can improve some exersizes for jumping next to squats, easy jump exersizes lik this are very helpfull.
and dont forget the core! it helps stabelizing everything, from landing till cutback. i work allot with a trx system
