I understand that both planks, sit-ups, and various other exercises are important in developing a strong core exercise routine. If you had to rank sit-ups and planks, which would you put on top? Any evidence?
Anyone have a great go to core building program? I am looking for something that isn’t the same routine every time.
Isometric vs dynamic, can’t compare the two.
I utilize a very diverse core program, but some of my favored movements are mountain climbers (think of that as dynamic planking), hanging vertical leg raises and twisting knee raises - on pull up bar, V ups, etc. Angle kicks at a heavy bag is a great core workout as well.
I do lots of core, but to be honest I combine with leg/hip/glute (for skating) so take what is useful, ignore the rest:
standard sit-upscrunches - feet planted, feet raisedplanks - 1 arm, 1 leg, 1arm+1legrussian twists - w/o and w/ medicine ballpush-ups on medicine ball, on reversed bosusquats - one leg, two leg on bosu, one leg on bosu (esp watching knee tracking)jackknivesdynamic leg switches (start in a raised knee position, crunch the core, then switch (like running knees-high) and stick the landing and hold it 5sec, get the arms in there too)all my skate drills which include a core element - search on youtube for speed skating basic position drills - those are killer on back & legs if you don’t engage your core right
I could go on and on here…
