just wondering if anyone tried a calisthenics workout plan, before starting a new martial art or some type of training.

not bad. any exercise is better than no exercise.
I did calesthenics for years before studying
exercise.

They tend to not push the heart rate up and keep it up long enough
for long-term training but are very good for starting up or instead of nothing

yeah because i wanted to start doing aikido but i want to be in good condition. so i am doing a calisthenics regime

aikido is great but it sure does NOT make you strong.

good thinking
