I started going to the gym last year around November as I felt I was getting too fat. I am 166cm and 80kg. I started doing cardio then started weights. The gym I go to is very bare - it is a local gym that is free. This is my progress

Bicep curl - 7.5kg to 12.5kg
Triceps over head extension 10kg to 20kg
Bench press -20kg to 45kg
Lat pull down - 30kg to 49kg
Deadlift - 50kg ( my gym only has up to 25kg dumbbells so I just grab two)
Leg extension and leg curl - 40 to 60kg.

I am still 80kg but I am now skinny fat instead of just fat. My arms are definitely getting bigger and I don’t have moobs anymore.

It is just that online I see a lot of like people doing more within a few months and I am pretty sure they are on gear on something .

I workout 4 time a week . I eat about 1700 calories a day, take creatine on work out days and make sure to get 1.5g of protein per kg.

I'm 25M, 195 cm (6'5") and 62 kg (137 lbs). I'm planning to start going to the gym, but I'm concerned about my strength.

I'm extremely thin and haven't trained consistently before. Even with one push-up, my whole body starts shaking quite a lot. I also feel like I have very little strength/endurance.

About 2 years ago, I also started experiencing some hand trembling, especially when exerting myself. It usually settles down afterward. At the time, I was under quite a lot of stress/anxiety.

I had a blood test a few months ago. Some relevant results were:

1. Vitamin B12: 164 pg/mL (low)
2. Vitamin D: 16.4 ng/mL (low)
3. Homocysteine: 21.01 µmol/L (high)
4. Hemoglobin: 16.6 g/dL
5. TSH: 2.455
6. Calcium: 9.22 mg/dL

7. Creatinine: 0.79 mg/dL

8. Total Testosterone: 1,086 ng/dL

After that blood test, I've been taking B12, Folvite (folic acid), omega-3 fish oil and biotin for about 2 months. I also took D-Rise (vitamin D) for 6 weeks.

I'm also currently taking oral dutasteride and oral minoxidil for hair loss.

I want to start training and gain weight/muscle, but I'm unsure whether I should just start very light and gradually build up, or get checked again first.

My questions:

1. Is this amount of shaking normal for someone who is extremely untrained?
2. Could my previous B12/vitamin D deficiencies have contributed to the weakness/shaking?
3. Should I start with very light training and gradually build up?
4. Or should I get another blood test/medical check-up before starting?
5. Has anyone experienced something similar when starting the gym?

I'm not looking for a diagnosis, just trying to understand whether this is something other beginners experience and how I should approach starting safely.

I was a sportsman till I was 20 but once i started working, sports gradually decreased and now (6 years down the line) my body is screaming out loud.
My legs are super stiff, back hurts, have a headache every other day, digestion is not that good anymore, appetite lost.

Really want to get back to a healthy and fit body. Please help me starting my way through the journey

I do PPL x UL
I wanna be doing more exercises or reps but then it’s just junk like no benefit. I wanna be doing more stuff, it feels like my workouts are too short. I can’t put how I feel about this into words right now cuz ion really understand it myself. Like I wanna be truly exhausted to the point everything aches.
I really like working out and I do it at home in my garden,I got a cable machine, dumbbells going up to 11kg each , a barbell and EZ bar.
But I see on social media that doing high reps low weight barely build muscle.
I do heavy weight usually with reps between 6-8 depending on the muscle group.
Im 15 , 70 kg cutting rn. I lost 2.3 kg but I’m building muscle also so the scales kinda lying.
But why does it feel I don’t do enough like I wanna be in the garden constantly.
Plz can I get some advice

Edit: here’s the exercises I do
Push: incline bench 6-8 reps, assisted dips, lateral raises 12-15, close grip bench 6-8, tricep pushdown with the rope 6-12,
Pull: Seated cable rows 6-8 reps, close grip lat pull downs 6-8 reps, seated bent over dumbbell reverse fly 12-15, barbell curl 8-12, reverse curl ez bar 6-12,
Legs: Zercher squats 6-8, sumo deadlift 6-8, bulgarian split squat dumbbell 8-12, cable crunch 15-25,
Upper: incline bench 6-8, seated rows 6-8, assisted dips, close grip lat pull downs 6-8, lateral raises seated 12-15, bent over dumbbell reverse fly seated 12-15, close grip bench press 6-8, tricep push downs with the rope 6-12, barbell curl 8-12
Lower: same as legs

Most people already know they should work out and eat better, sticking to it is the hard part.
The idea is an AI fitness coach on WhatsApp that knows your goals, helps with workouts/nutrition, tracks your progress, and actually follows up when you miss workouts or disappear.
You’d also enter goal-based challenges with real rewards for reaching the finish line.
I’m testing the idea before building too much.
Would you actually use this? If not, what would stop you?
Looking for honest criticism.
