Training Thoughts.... Plus, Leg Day Is Dead. I Killed it!

Day 4 into the new year and I'm really pleased with how things are going training wise. I have decided to break my training focus down into quarters, but I still have not fully planned it all out. However, I know for this first quarter I will be focusing on shredding fat, therefore I have already lightened my weight load and increased my reps. Some may be under the impression that lifting lighter load for more reps is easy, but they are wrong. I'd rather be lifting heavy. Anyhoo... I'm also incorporating some light cardio between reps. Either jogging in place, jumping jacks, or pretend jump rope. I also do 20 mins of cardio before lifting and 10-15 mins of cardio after my session is done. I've been following a split schedule that 3reFit created and we discussed that since my goals have changed a bit, then that split schedule may change a bit. In my brain I will be doing legs every 4 days and back every 4 days and other body part which are to be determined as I go along on other days along with a lot of cardio. So, today was leg day and in the middle of my lunge work, this really buff dude came up to me and asked if he could work in his sets, so I said yes. For those of you who are not familiar with someone "working in" it means that after you get done doing a set, they get their set in and so on. The only thing that I don't like about it is, it makes me feel rushed, and I despise feeling rushed. Anyways, it worked out okay, I guess. I just don't like the distraction or having to wait for others while they finish because when I'm ready to go, I'm ready to go. Good thing is, he didn't change the weight I had on the bar which made that go a lot smoother. Maybe it's just me, but it's kind of creepy working out with people you don't know. I mean he just sat there watching me do my lunges,  I walked the gym while he was doing his squats. LOL! It was just weird. Anyways, if you have any suggestions for me regarding my goals of shredding fat, building muscle, and keeping my running up let me know. The two seem to counter each other but I love both lifting and running. I will continue to do both as I am trying to build both simultaneously. I think I can with phenomenal results. We will see!
