That which does not kill you makes you stronger also
.Seriously I agree w/SupplementGuy & onlyme in that you can or will be able to train the muscles again within a few days but maybe not at full capacity you usually can w/the soreness.It's what i've always done.Here's a story for an example of my experience w/soreness & how I never get sore after the first time soreness.Remember this is "my" personal experience & the way my body works.
When I was 16/17 yrs old I weighred 175 lbs.I traineed w/a fellow that was maybe 4-5 yrs. older than me.One day after we had worked out the evening before he was telling me how sore he was.I told him what I stated here how I never get sore again after the first initial soreness.Well he had me do a leg workout!I used 175 lbs. & did reps w/it from 20 reps all the way down to a single repetition.1st set 175lbs x 20 reps,2nd set 175 lbs x 19 reps,3rd set 175 lbs x 18 reps etc. all the down to just 1 rep.We also did the usual thigh curls,lunges,extensions etc. but just regular straight set style.Anyway, the next day he was sore as hell yet I just had a dull ache in my muscles, nothing that would hinder me from doing any daily activities etc.
As onlyme said & I feel the same way....what works for me may be unusual & maybe won't work for you because everyone is different.Theres a few things that are freaky about me & my body in regards to weight training but i'm not complaining, makes it easier for me
.To each their own.
