When I spar I try to get inside but I struggle because they are always jabbing and moving. Is there any drills or workouts to work on speed and get inside fast
Keep punching and coming forward. I like to use my punches as distractions while I inch forward. That doesn't mean to throw random punches. Still throw smart. Stay on them all the time and they will get frustrated which will eventually lead to them messing up.
Move laterally instead of vertically. Keep the targets on your own body a minimum. Establish a pace with the jab then disrupt it with follow up 1-2's at a varied speed. Keep your jabbing hip on the outside of your opponents, to cut the distance and enable you to 'get off first'.
Tyson was a master at it.ive coached a lad at our club to zig zag as he comes in which makes whover he's sparring or fighting, back up to find room.
Move laterally .:good when I boxed I liked to fight off and behind my jab and loved shorter fighters who came straight in but lateral and head movement and id have to think more and move myself.
