I tend to do BW exercises within the warm-up. Warm-ups are quite ... hmmm.... what would I call it . . . "warming-up" but they do the job.
3-4 movements or combines like burpees or others, performed using different protocales
4 exercises x 30 sec each no rest... 1 min rest and repeat 3-4 times in circuit fashion.
or 3 x 3 min for combines with a min rest inbetween
that gives you anything from (depaending from your level of fintess) 6 - 9 minutes of solid exercise.
you could also try (if times permits) do 1-2 session/week of BW routines - they do not have to be long, anything from 30-45 min MAX.
Sometimes, just for a weight control, some 15 min intensive bodyweight routine a couple of times a week makes you freakishly fit and lean (just a little perk on the side).
I always treat it as a Active Recovery... or ... getting back to shape - both in terms of vanity as well as cardio-vascular fitness.
good way of doing cardio ... without actually doing cardio - if you know what I mean.
+ you keep your muscles on... unlike while doing "standard" cardio sessions where you waste your hard work and muscle mass.
that's how I utilise BW exercises.
Useful tool, however, the way I see it... quite flexible! Make it work for you! you will NOT easily overdo bodyweight.
you can only gain here!
maybe some people have different ways of using BW exercises . . . I'd be happy to learn
