25 Str a Day? Just how long can you play and what is your Atk lvl? Oh, an items list of things you need/should include: Iron Total Helm, Str and Power Ammy, Iron Plate, Scimmys Iron - Rune, Iron Kite, Green D Hide Vamps and Chaps, SoS Boots, Team Cape, Explorer Ring, Maple Short*, Str Potions, Loads of Food. If you plan to train Range ANY higher than 40 (40 being the min for Green D Hide) then buy a Maple Long also so you can add the Sight for it, as it's overpowered in F2p.
Assuming you are not staying 1 Atk, do Vampire Slayer to get 20 Atk. As you are staying 1 minute, get 40 Range for Green D Hide, that's the best Def bonus in F2p to get a 1 Fragrant Property. If your Atk/Str is large enough, you won't lvl in any way. I strongly suggest getting Range upward, even if you only need the Def increase of this Green D Hide. Same thing for Magic unless you like to walk. 25 for Varrock Tele, although I get 37 to get Fally. If your Atk/Str is large enough, then you won't lvl in any way. I do so since I have come to rely on teles, if you aren't lazy like me, skip this. 2 Str Potions and the rest food (Lobbys are inexpensive at the moment, make the most.)
Lumby Catacombs are fantastic for coaching, just don't finish the Blood Pact quest, since you get two Def. By doing this quest, you receive Kayle's Sling, and it will be a godsend for cheap individuals because it literally provides you free Range Xp. Remain in the Catacombs until 30 Atk/Str and Range. Should be pretty obvious what to prepare on. .
Head to Monks by Edgeville until 45 Atk and Str. Train Str here before 70 or even 80. In addition, I recomend you visit Hill Giants/Flesh Crawlers until 99 Str. In the end you ought to be something like: 50 Atk, 99 Str, 1 Def (Or 2 Def in case you didn't listen and COMPLETED Blood Pact or destroyed your pure), 40 Range, 31 Prayer, 37 Magic.
