High intensity interval training and/or strength training. It should hurt (but not injure) and you should push through it. No pain, no gain.
Everybody please take this one with a YUGE caveat:
It should hurt in the CENTER OF THE MUSCLE, called the belly, NOT AT THE TENDONS WHERE IT CONNECTS TO BONE. And NOT IN THE JOINTS! Whatever you do, DO NOT "push past pain" in the joints.
NOT THE JOINTS. In the joints, no pain IS gain. Repeat forever: NO PAIN, THAT'S SANE.
Pain in tendons (which join muscle to bone) or in ligaments (which join bone to bone) can indicate microtearing of fibers that take many weeks to fully heal instead of a few days like muscle, and do so with fibrous scar tissue made of microfibrils laid down haphazardly and of lower grade than the correctly aligned original fibers.
Pain at muscle insertions can also indicate microavulsion of the periosteum, which is tissue tightly enwrapping bones and is richly innervated. If avulsed it takes months to fully heal, does so with scar tissue tugging on tiny nerve endings, and so tends to provide pain signals indefinitely.
The MUSCLE BELLY can burn and flutter and feel weak and you can keep going. Rock on, iron man and titanium woman! (The only two choices BTW)
Pain the next day or two after a workout is of course also normal, as the body repairs the intentional damage done in the muscle belly. With consistency, hypertrophy (bigger, stronger muscle tissue) results. With inconsistency, you get the pain, but no gain. :)
