Fitness Log #1 - Arms-Week0

So... after a long hiatus I decided to start gymming properly again. Well, I was already gymming since I started work at the pathetic gym near my workplace, but it was missing a Squat rack and a Bench rack, so I couldn't do those two all-important compound lifts. Plus I still stuck to my 3 day mixed routine, which wasn't giving me any noticeable gains, apart from a slight increase in definition in my arms.
During this time, there was a period of maybe a month where I increased my diet too, eating an extra snack each day of usually chicken fillets and drinking a banana milkshake every afternoon. I'm not sure how much that really helped apart from packing on some stubborn tummy fat, but I did gain 3 kg in the 3 months.

Now, I will be starting on a 4 day split routine - chest, arms, rest, back, shoulders (I do squats with chest day, and crunches with back day) - and hope this routine gives me more gains. I'll evaluate the overall routine again in 3 months. I'm a bit lazy to up my diet again, due to the extra costs/time, but I know this will limit my gains too. Sigh. It's tough to get bigger.

I wanted to log all my workouts with my thoughts so that I can have a clearer idea of my progression.

Arms - Week 0
This is Week 0 because it isn't the first full week. And I like working on arms.

Straight Barbell Bicep Curls - 25kg (up)
Reps: 6, 6, 6
This weight is too light but it was the heaviest one available in the pathetic gym. Next week onwards I'll go to a proper one and start upping the weights. I'm a little concerned about the strain to my wrist though - back in Boston when I was lifting too, I developed an acute pain to my wrist because of the straight bar. I think I will continue with the straight bar for a while, till the pain returns, then I'll use the EZ bar.

DB tricep curls - 15kg (up)
Reps: 6 6 6
Not used to working my triceps so started lighter to be safe, and also get used to the exercise. This is the one-handed variation where I curl above my head to behind my neck. Feels great for now, but not sure what happens when I hit a weight too heavy for me. Will I drop the weight?

Alternate DB bicep curls - 15kg (stay)
Reps: 6 6 6
Though I completed the reps, I find I cheat a lot on the form by swinging my body to pull the weight up. I think I'll stay on this weight first to improve my form, and once I can lift the full reps without swinging and purely using my arms, I will up the weight.

Hammer curls - 15kg (down)
Reps: 6 6 6
Similar to the above, I cheat on the form. I think the weight is too heavy by this time into my workout, so I have to go lower. I want to get perfect reps out each time, no point cheating myself and going up a weight when I compromise form. Ultimately, my goal is for bigger muscles, not for bragging rights of lifting a heavier weight.
I do want to replace this exercise with another tricep exercise such as Closed Grip Bench Press, maybe I'll do that for the next workout.
