Hi guyz. This is my way of jungling/creeping Tryndamere. He is one of my favorife champs. He's often banned in Ranked games soo I use this build for normal games very often.
I reccomand this build for junglers like Tryndamere and Olaf.
This is my first guide soo i'm not a pro in doing things like this.

For Runes I use Armor Penetration Marks,Critical Chance Seales,I use Cooldown Reduction Glyphs and for Quintessence Armor Penetration. Tryndamere needs lost of Armor Pen couse he can get easly counterd by Thormail soo he needs to do more dmg to Champions with high armor.
Critical Chance Seals are for getting Rage more easier and it can speed up your Jungling route.Cooldown Reduction Glyphs are for spamming your BloodLust an it can really save u in some situations.

For my Masteries i take 19 points in Offense and 11 poinst in Utility.
In Offense i get Smite and Deadliness. I get 4 points in Sorcery and 2 point in Offensive Mastery(u deal more dmg to Minions and Creeps)and i get 3 pints in Sunder. After that i go for Brute Force and Lethality. I utility i go for Good Hands and Haste,then i get Awereness and Greed.I get Utility Mastery right after that(increses neutral monster buff duration)

Skill Sequence! I get my BloodLust point every time possible,soo i max it firstly. At lvl 5 i get one point in Mocking Shout.As i max my Bloodlust at lvl 9 i do the same with Spinning Slash. Soo it looks like this:
LVL 1:Q
LVL 2:E
LVL 3:Q
LVL 4:E
LVL 5:W
LVL 6:R
LVL 7:Q
LVL 8:E
LVL 9:Q
LVL 10:E
LVL 11:R
LVL 12:Q Max
LVL 13:E Max
LVL 14:W
LVL 15:W
LVL 16:R
LVL 17:W
LVL 18:W

This is how I Max my skills.

For Summoner spells i use Ghost and Smite. I used to use Heal and Smite at lower lvls couse i didn't have my runes. Ghost is good for chasing. If u play Ranked games with Tryndamere and u see that the enemy team has lost of Crowd Control(stuns,fears,Slows,knocks) it's good to get Smite and Cleanse.

Tryndamere is a very good champion with lost of pros,but he has some cons too.

PROS:
-Invincibility
-Can heal with BloodLust
-He can cast his ulty even when he is Stuneed or Feared.
-Can Slow and Reduce Dmg to Champs in an Area near him(Mocking Shout)
CONS:
-He's preety bad and squishy in early game
-Low crit and lifesteal early on
-Needs to farm a lot
-He needs items that cost prrety much(Infinity Edge,Phantom Dancer,Bloodthirster)

For Jungling/Creeping I have 2 Staring items. You can start or with a Vampiric Scepteror with a Cloth ArmorU continue getting a Wriggle's Lanterand Berserker's Greaves. After the Berserker's Greaes i get a bigger item like BloodThisterand an Infinity Edge. If their team has tanky champs(Taric,Alistar,Amumu,Morde,Nasus and OLaf or Udyr) I reccomand to get a Brutalizereven if i don't buy it very oftenly. After the Infinity Edge i go for a Phantom Dancer. After it i go for another Bloodthirster and a Phantom Dancer again.
Against Squishys I use Berserker's Greaves,BloodThirster,Infinity Edge,Phantom Dancer.BloodThirster and another Phantom Dancer.
Against Tanky Champions I use Berserker's Greaves, BloodThiter,Infinity Edge,Youmuu's GhostBlade,Phantom Dancer and a BloodThister.

Tryndamere is a great farmer. When u see lost of minions coming towards You just spam Spinning Splash and u will get lost of minions kills. Tryndamere needs to farm very well early game soo he can use his heal when attacked by champs or turrets. Using your BloodLust is a great way to save yourself if u dont have your Undying Rage or if it is on Cooldown.
Farm a lot when your Ultymate is on cooldown soo u can easyly come in teamfight with your heal ready. Tryndamere can also buy and early game iamit couse he needs farming and it deals spalsh dmg to minnions and Champions. Most early game bad farmers need this item too.

The last thing i wanna is,U have to be carefull to don't focus tanks abd champs with Thormailcouse they will counter u very easly. U just have to focus squishys and the main DMG dealers. Get tanks and guyz with Thormail in the end.


Good Luck and Have Fun
Hope u enyoed
