This was quite bad day today in the gym and that too my first day. I vomited after doing just 20 sit ups in the final session of the day.
I'm newbie in fitness and don't know too much terms and i don't exercised previously. I am programmer by profession.
I did few lifts, presses, push ups, pull ups, stretching. Which affected nothing to me apart from little muscle pain due reason being first day in gym i believe. I had done gym 4years back for only 4months approx. Now i thought to start again.
Exercise followed: In weight based: 3 sets with increasing weight by one slab. Like as below 1st set: 15kg 15times 2nd set: 30-40kg 12times 3rd set: same or more 10times
In other: 20times Like 20 Sit ups or stretching variations.
As i was exhausted after almost 50 min of exercises, i asked trainer to leave and he instructed me to do last two things, 20 sit ups and hand crunches (for fist strengthening) but after doing sit ups my body started weird feeling. I felt faints and un easy breathing. After few minutes of rest i felt like vomit and after vomiting all was well.
In vomit, it was water and few food particles from dinner yesterday.
My question are: 1. Why it happened after sit ups only? 2. What precaution i must take so if my trainer is going wrong i can prevent hurting myself?
