At the beginning of the year my main focus to work out my butt and legs. A couple weeks later I realized that I really lacked upper body strength so that became one of my focuses aswell. I didn't use a specific workout plan when I was in the weight room but I would use workouts that I know and ones that I learned from my peers while in the weight room.
For my legs and butt I went from squatting 10lbs plates to 25lbs plates as the semester progressed. I also did kickbacks and other workouts for my legs and butt on the cable machines. Sajini and Puneets butt workouts were part of what I did in the weight room aswell. I also did jumpsquats squats with leg raises and went from lunging and squating with an empty bar to doing 15lbs plates. I haven't seen too much change in my butt yet because that takes time but my legs have firmed and toned up a lot more than they were at the start of the semester and I'm happy with that.
As for my arms I did workouts like biceps curls 10lbs to 15lbs now at the minimum and lifting that focused on triceps. I used the cable machine and did the workouts that it shows you aswell. I honestly don't know the names of a lot of the workouts that I did I just know how to do them. One achievement I made was the bench that you sit on and lay your arms down ( i don't know what it's called :$) but i wasn't able to even lift the bar at that position and now I can curl it! I also did some pec workouts (again don't know the names). My arms aren't as slim and tones as I want yet but it's an improvement from the start of the year till now for sure. They look and feel more firm and I almost do a proper push-up now! And I can do 25 modified push-ups. I was only able to hold plank for 45 secs max before and now I can hold it for 1min15secs which means my core strength has improved aswell.
I still have a lot of work to do to achieve my goals but I'm pretty happy with the progress I've made so far. I still have to keep working for it though :)
