Erica and I have been lifting together for around a month now to augment our aikido training, improve our general health and spend time together doing something fun. We each have different specific goals for our lifting though and with the help of an excellent trainer are already beginning to see results. My question is this...can anyone explain to me why (physiologically) results differ due to high weight low reps/low weight high reps? Also, why does recovery time between sets make such a difference. I'm working to bulk up so I'm doing sets of 8-10 reps with a weight that makes me push for the last rep and she's looking to "tone" so she's doing sets of 15 that make her push for the last rep. She will rest for 1 minute between sets while I've been told to wait 2 to 3 min between. We both get an excellent "pump" from our workout and only mild soreness the day after. Our energy level the rest of the week is up even more than when we were just doing the aikido alone.
The whole point of the question, I guess, is just to satisfy my curiosity. As I said, we're already seeing results and I've had nothing but good reports about my trainer (gym provided) so I'm not questioning his tactics. I just like to understand why things work the way they do.
edit: Forgot to mention that there are some exercises that we'll both do 15 reps per set on that only work very small muscle groups or are meant to pre-fatigue a certain body part. My back is still not 100% from falling off that roof in '04 so my leg day is almost a micro-management point for HR (the trainer) and he has me prefatigue the legs so that it doesn't take as much weight to give my legs a good work out.
