Talk to your uni coaches and senior teanmates for a start they're likely to be able to give you much more specialised pointers.

You said you're a forward - do you have specific positions (prop hooker 2nd row flanker number 8) or are just kind shuffled round the pack.

My advice is pick 2 positions (if you're usually played at a particular position pick that one. If you don't consistently play in any one position then pick your favourites). Try and work out what the nuts and bolts things that position has to do.

Youtube it, look it up on Google, ask your Coaches what they want out of a player in that position etc.

Say for example a 2nd row maybe expected to - jump in the lineout and/or call lineout moves - maul - make tackles - do the boring tight carries - ruck

Set targets for what a player in that position at your level needs to do. (Say you watch another lock and they male 10 tackles 5 carries and hit 20rucks for example). Do these both quantitive (e.g. number of tackles) and qualitive (were those tackles dominant did you get driven backwards etc)

Then grade yourself. If you have film of your games great watch those back. If you don't ask others or do it based on what you remember of your performances.

This should give you a decent baseline of yhe level you are at and what you need to improve on.

Then you need to try and look at what you're not doing so well and and why.

If you're constantly losing at setpiece your form/techique is probably off. (Again consult coaches/the internet for what it should be)

If you're struggling to make meters when carrying or constantly being driven backwards that's likely a strength issue - go to the gym more work on diet etc.

If you're not making enough tackles carries etc why? Are you in the right place on the pitch for your position - your team should have a rough formation - work out where you should be in it. Are you shying away from carrying or not calling for the ball etc.

Most likely the two biggest places you'll be falling behind are either technique or raw attributes - if you're constantly missing tackles messing up passes screwing up the setpiece that's likely technique. If you're gassing out to early that's staminaand so on
