Once upon a time I trained for size, which I suppose is my base, but then I didn't lift for a long time due to an injury and surgeries. These days I go for utility, minimize wear and tear, and just feel good. I don't want to look huge, it's not my thing. Don't get me wrong, I like lifting, but I work within my limitations. Currently, I'm nearly 15lbs lighter than in that photo, but I'll gain 5-8lbs once I'm lifting again, but def not concerned with training for size.
These days I'm not lifting a lot, in weight or frequency. Freaky look? lol. To each their own, but I'd rather spend my time fly fishing, hiking, and camping, so it really doesn't fit with my lifestyle. Plus, I don't want to spend that much time in the gym. Different focus and priorities, that's all.
I've always been a fan of raw power and explosive strength, so powerlifting, weightlifting, and some strongman movements appeal to me, and I know some guys who are incredibly strong for their size. An acquaintance of mine is around 160lbs (last competition his weigh in was 145) and his deadlift is over 600lbs, his squat is nearly as much. Personally, were I a lot younger, I would focus on weightlifting and powerlifting. Another guy I met at a different gym was 5'8 155lbs and would do 245lb power cleans with perfect form, and the timing of a fucking metronome. He would do 8 reps, take a rest, then repeat 2 more times like it was nothing. The explosive strength it takes to do that is awesome.
