It is not unusual for a beginner to pick up a fitness programme and quit shortly after because they are unable to tolerate the soreness and ache that develops after. The soreness that comes with training is perfectly normal and your body will need some time to adapt to the stresses of a fitness programme.
Stick to your training programme no matter what and within 8 weeks, your aches and pain will become less painful and more manageable. It needs to be understood that it takes time for muscle tissue to adapt and become stronger to the point where one can endure an intense session without excessive soreness the next day.
The take-home point is: stick to your programme even if it hurts; you’ll be fine in 2 months or so.
