<p>Hey, some people gain weight fast when they first get into college b/c the buffet style dining and greater food selection leads to consuming a lot more calories. 145 is the opposite of a fat person; in fact it’s probably healthier that you put on that weight.</p>
<p>I’ll make a few comments.</p>
<ol>
<li><p>You can go from skinny to buff if you want to. Do some research online; this topic has been covered several thousand times over.</p></li>
<li><p>Lifting accounts for 20% of your gains while your diet accounts for 80%. Obviously those numbers were pulled from the sky but diet is supremely important. If you’re lifting and not eating a ton of food, you’re just spinning your wheels and going nowhere.</p></li>
<li><p>A trainer may be a good idea, but I know countless idiot trainers. I also know several awesome trainers. The problem is, if you are just starting out and learning for the first time, you won’t know if the guy knows proper form or not. You could try a trainer but I would scour the google/ the internet/ lifting message boards for proper form either way.</p></li>
</ol>
<p>The only way you’ll hurt yourself in the gym is with improper form. If you lift correctly, then you’ll be fine; in fact weight lifting actually improves joint strength and general flexibility and has about a thousand health benefits. So yeah, I agree it’s hard to get injured, compared to something like running, where a pulled/rolled/nagging something might occur every 3-4 months - but I wouldn’t say injuries never happen.</p>
