When I'm going hard, lifting 5-6 days a week, every 10-12 weeks or so. I'll take a deload week where I dont lift jack shit the whole week. That following week when I get back to it, I always feel stronger. I went hard for 7-8 years and was insanely fucking strong. Then the last year I turned into a lazy POS and was in the gym a few times a month, partly due to work, but more so just being lazy and or losing the drive. I was at 425 on a 1rm on flat, 385 incline, 245 seated OH press. Now, I could probably hit a 1rm of 365 flat, 315 incline and 185 OH press. Also, this may sound strange, but my weight at 300-315lbs when I'm working out 5-6 days a week doesnt feel like I'm heavy, I feel solid af.
Same weight while being a lazy POS, I feel like a fat ass.
