Body Weight Change?

Yesterday I weighed 79.5KG.
This morning 76.5 ..

What the!?!

I went from an all-time high in weight to dropping to my lowest since returning from NZ on new years day (77).

Possible contributing factors: drank beer on Saturday night (today is Tuesday) perhaps their was built-up water retention from this, and could have contributed to lack of muscle growth? Unsure.

Also, I did a work-out yesterday morning and played playground ball in the afternoon - basically my calorie usage went up, and I didn't increase my calorie consumption. I failed to even record what I ate for the day yesterday. BIG fail on my part.

Perhaps partial laziness? Perhaps didn't want to think about it? I just wanted a day off from everything - I had been seeing progress to date and it had been working so just go with the flow and try to keep things in order. That's a mistake and I need more mental focus. Need to record calorie and protein intake on a daily basis. Need to make sure I am getting this right so that in the future if I am seeing lack of progress in my workout I can look back and see what I may have done wrong. Diet is a huge part of this.

What else?

Oh yeah, yesterdays workout - I had my first fail since beginning the weights in late December.

Squat: 70KG - done - have found squats easier since switching from sneakers to chucks
Bench: 52.5 - fail. The weights seemed impossibly heavy. Also, on second and third sets I inadvertently lifted my left leg off the ground to try and gain power. I should be pushing them against the ground to get strength from my legs and upper body.

I am sure that as I lift heavier and heavier weights, my technique will improve. If I do not, it will make it harder to lift the heavier weights. Gotta watch this space.

I am really looking forward to when I can bench 60KG. This will be a really positive sign of achievement and getting stronger.

Deadlift - 90KG - I did 90KG last time as well, but didn't feel confident so I wanted to do it again. This time felt better, my form was better. I didn't feel like I nearly injured my back as I did last time. So now I am confident to return. My only issue is, I took about 10 seconds between reps. A lot of this was due to the mental strain of the weights. I was scared to lift them. I gotta overcome this and power through next time.

One of the reasons it has been taking me time between reps is that I need to 'reset' my form. That is, stand-up, re-grab the bar, and go back down. Not only am I physically resetting, but this is leading to my mental re-set between reps as well. Which takes more time. Just need to improve basically, which I am sure will happen as I get used to the weights.

Off-day today. Weights tomorrow. Looking forward to it.
