Even they harm themselves.See I am going to tell you why that happenings....
1.Physic of Men and Women are totally different. With proper workout and weight training Women may develop their strength bt its impossible to build muscle rather they inject MEN HORMONES .
2. Everyone's goal is different.Somebody's goal is weight gaining and somebody's weight lose.So how with same routine you achieve your goals. Thats not possible.
3. As a sports also some are going for BODYBUILDING, MEN PHYSIC and some are going for POWERLIFTING.Interesting think is ,if you noticed that people you find their body structure is totally different. POWERLIFTERS are much more bulky than BODYBUILDERS.
4. In BODYBUILDING also some one like bulky mass and some one like muscle.So its next to impossible if they follow same plan.
With that examples I think you people understand that same workout plan is never ever worked for your body. Fake GURUS are hugely present in this respective field. Some also influenced you badly but you people do one thing only, always visit your nearest gym and after understanding they are certified or not join them.without proper guide and training never do any kind of exercise.One more thing focus on NUTRITION and avoid maximum SUPPLIMENT.
STAY HEALTHY AND STRONG.
