You don't necessarily have to wait till the soreness leaves - Typically you just need to make sure you work a DIFFERENT set of muscles. If you did all at once, you will want to wait or you could cause greater muscle tearing (normal process for building strength, but too much too fast can injure). If you did, say, just your glutes (butt) and biceps (front upper arm), you could do a work-out for legs and triceps (back upper arm). Just an example. You want to aim to alternate your muscle groups in strength training. If you're just sore all over, try the Epsom salt bath and give yourself another day or so, or you could just do an aerobic exercise (like treadmill or swimming). If you're new to exercise, a good "rule of thumb" is 120 beats per minute (bpm) heartrate sustained over 20 minutes (for cardio/heart workouts). That usually works out to about 30 minutes if you add 5 minutes to get up to that rate, and 5 minutes to cool down from that rate. :) :) There are plenty of active folks on this site (WAY better than me!) who could comment. There is at least one thread I know of, too, where you could log your exercise and invite accountability. I'll try to find the link and post next. Good for motivation! ;)
