Hello. I've made my own fitness arms buildening regime. Thing.

Everynight I do:

40 x dumbbells curls,
40 x hammer lifts with dumbbells,
40 x dumbbell shoulder press,

I then do 30 of the above, the 20 then 10.

How is this regime? I've noticed my arms and shoulders have got a lot better. I've been doing 30 of each then descending in 10s for about 2 months now and I've just knocked it up to 40 then descending in 10s. I do a lot of cardio, running pretty much every free night.
