Labeled as "boot camp" and "toning" for women, it's really just progressive calisthenic routines and is just as good for men, and for any age. Calisthenics don't care about gender. These sorts of cali routines combine cardio, so doing this sort of program for several weeks covers both, while keeping your muscles in use and building stamina and agility.
Doing it daily in a group, or with a group of pals, works best but anybody ought to be able to follow this path which begins fairly easy, about an hour daily, and ramps up in challenge but not in time spent.
For each week, you would do the routine 5 days. It doesn't require a gym or any special equipment besides hand weights. If you start now, you should be "well-toned" and fit by Labor Day: Get Toned Fast
Right here and now I issue a challenge to some of our guy readers who are sarcastic or dismissive about structured fitness to give this a 6-week try at 5 days per week, and then get back to me with a report. Nothing to lose, and no need to tell anybody it's a girl program. Mr. Bliss is doing it with me, before work each morning, as a summer break from his usual gym routine.
When I first encountered this program, I had to check out what they meant by some of the terms on Youtube. Try the Turkish Get-Up. I'd advise against the crunches. Do V-ups instead.
