Recently I've started to bend my knees a lot more and really lean forward in my shots.
I've also really improved my return by putting a lot of pressure on my toes (like a goalkeeper), bending my knees and moving my weight forward as fast as possible.
My physical condition is good, I've always been able to play best of 5 sets without to much trouble.
But by using my new style of footwork on every single ball I hit my legs get tired when the rally's are long and at a high pace.
Sooo, I need some home exercises for me lower body (legs etc) to add to my stomach- and upper body muscle routine.
(preferable without weights because then I don't have to buy any

)
