| i have two bulging discs, and light weight lifting for 30minutes and a one round of crossfit really helps me (my studio does 3, i tried two but it proved too much at the moment), combined with gravity boots after. the thing about crossfit is that its a muscle / indurance mix. almost army style training really. it puts you in an anerobic state, lowering the oxygen your cells can consume, forcing your body to build more resiliant cells and muscle fibre. one thing to note: often crossfit mixes different routines, so if you have a back issue, make sure you avoid ones that involve excessice back strain such as planks, until your back is completely healed. other than that its healtheir than weight lifting for the average person, no heavy weights involved and its full body, so all the little muscles get to work too. its time efficient too, 60 minutes and done. weight lifting can stretch for hours as you advance. with crossfit, you just reduce your rest period if you want more intensity. personally i do a mix of both, and keep my training under 90minutes two times a week. |
