📋 About This Mod

Background I started a character for my latest 'Lets Play Skyrim' video series and deliberately made him very skinny as his back story was that of a scholar, not a warrior. I felt it would be an interesting experience to play someone truly unsuited to an adventurers life when he first picked up a sword. However a number of people suggested that as he progressed through the trials an troubles that Skyrim threw at him, his muscles should grow over time due to the constant physical training he was receiving.

Thus was born the idea of 'Pumping Iron'. Oh and the name is a nod to the old Arnold movie of the same name.

Overview Every time your character gets a skill increase in a combat skill (or smithing) his muscles will be considered to have been trained a little. The more skill increases, the more training.

When a 'trained' character sleeps, his muscles will grow ever so slightly.

Now this effect is not fast, and will require a lot of training, and a lot of sleeping. To go from the very smallest body size to the very largest will probably require that you take most of the combat skills all the way to 100 (or a few of them beyond 100 if you are using the uncapper mod). It will also require time. There is a limit to how much your body will grow in a single night, and you will need reasonable and regular nights sleep. At least 5 or 6 hours for a normal training day, and up to 10 for a seriously intense day of fighting.

Oh, and the effects of training do wear off with time so get regular sleep or you will lose some of that hard work.

Currently you won't lose muscle ever, but you just lose the 'training' you did that might grow your muscles. This may change with updates.

There is also an MCM entry showing you your current body size (0 being the smallest and 100 being the largest) as well as your current level of training (potential growth).

Possible future developments I would like to integrate it with mods like Realistic Needs and Diseases so that you must be well fed and watered to gain properly.

I would also like to add muscle loss due to inaction or disease.

Requirements SKSE is required! Click here for details on how to install.

Installation Just use NMM, download with manager and activate. Or if you manually install, just extract the rar file into your data folder.

Load order should not matter.

Compatability This mod changes the size value for your character but does not touch the models. In theory it should work with any models that use the size slider on the race menu.
