It's almost been 2 years since I moved to university and lost touch with boxing.
Age 20, 6'3", 12st (ish)

I had an itch i couldn't scratch and am now getting back to my true love boxing

I am starting again (yesterday) my fitness is better than most average people, but needs to improve while my speed and reflexes are still good.

However my footwork is poor, and my new gym teaches differently,

I need to spend time on the bag, to get use to hitting the bags again

I'd appreciate some help getting my footwork up to standard, especially while punching and moving at the same time
ie ,bringing the jab and front leg forward, then right leg forward before using the cross

Some footwork exercises

I also need to learn to punch and move at the same time

Also one of the coaches says I am jumping when moving my feet, and when i go forward i should go front foot forward, land toe then heel then bring the back foot forward

Hitting the bag also feels so alien to me

I know in a couple of weeks I'll be able to box well again I hope

Also I need a fitness plan to fit around work, i work mon-fri with gym on mon-fri

I have access to weights and a pushbike

thanks for any advice
