My apologies if this isn't the proper forum for this.
I have known for years, i feel amazing when i spend time in the sun, and even tanning beds. Well, recently, i kind of realized i have had a few workouts this past 2 weeks where i felt stronger than i have been feeling lately, on my typical lifts. It just so happened, I spent some time out at my pool an hour or two before hitting the gym on those specific days. My next session was a normal day, gym after work, no chance for any sun. I had a very "typical" day. Now at this point, I had no expectations. Just to point out, I am cutting and have been for a couple months. Following a 5x5 full body 3x/week routine. (IceCreamFitness 5x5). Just this Saturday, again I went out to the pool prior to hitting the gym. This time, admittedly, mentally i was curious if it would effect my session. I got to the gym and i was actually semi worn down. Yet, i matched a PR on bench press (215lbs 5x5) and actually did a set of 220lbs on my 5th set. Now, i had no spotter, so i was very confident I'd complete the set.
Could there even be any reason for this or am I completely off my rocker? . Can sun exposure/vit D have such immediate effects on strength/percormance?
A quick Google of Vitamin D deficiency showed this: 2.) Muscle weakness - According to Michael F. Holick, a leading vitamin D expert, muscle weakness is usually caused by vitamin D deficiency because for skeletal muscles to function properly, their vitamin D receptors must be sustained by vitamin D.
FWIW, I supplement anywhere from 2000ui to 5000ui Vit D3, daily... I have never had my levels checked though.
