If I recall correctly, it's somewhat normal to gain some weight when first starting weightlifting. Is that right? If so, how long does it take the body to adjust to the new routine? (And will the day-after soreness/aching also either go away or be greatly reduced? When I get out of bed, I swear that I magically turned 88 overnight.)

In terms of what I'm doing, I just bumped up my CF from twice a week to three times, which is what I'd like to do going forward. Two days are strength training (focusing on one lift) with a warmup and sometimes a post-lifting exercises (effing burpees) and one day is HIIT. (I also do tae kwon do three times each week, and I've just begun walking in the morning as well.)

Thanks in advance...
