Pull-ups, the fundamental pulling exercise in calisthenics, is a staple in any good program. Being able to do pull-ups in your own home doesn't require expensive equipment like a squat rack or tower. This handy pull-up bar uses leverage to hang safely on any standard door frame, so there's no need for installation with screws or bolts. Simply hang it up on top of the door frame, make sure it's secure, and away you go with your pull-up routine.
Holds up to 300 lbs and fits all standard doorways 24 - 32 inches wide. Can also be placed on the ground to be used as push-up grips and parallettes (hence the name "Total upper body workout bar").
While horizontal pressing movements like push-ups are essential in calisthenics, the vertical pressing movements, known as "dips," are just as important. To truly advance in calisthenics, you're going to want a solid and sturdy set of dip bars so you can learn moves such as explosive dips, L-Sits, handstands and handstand push-ups on the parallel bars. The Equalizer is your best option for all of these.
Supports up to 400 lbs. Can also be used for modified pull-ups (feet resting on ground for assistance) as a progression to full pull-ups. Includes a DVD and eBook with training programs.
Performing cardiovascular exercise with calisthenics can be achieved with many exercises: jumping jacks, mountain climbers, burpees and high knees, just to name a few. But one of the most effective yet often overlooked cardio exercises is jumping rope. This "speed rope" is perfect for beginners. It's light weight for fast jumping, easy to travel with and adjustable for any height. A perfect and cheap addition to everyone's calisthenics arsenal.
Many calisthenics progressions can benefit from the use of an assistance band, whether you're working towards the basic pull-up or the full front-lever. Assistance bands allow you to work on progressions that are currently too difficult for you by reducing the amount of resistance felt by gravity.
By simply placing the band over a bar and looping it through itself, you now have a sturdy loop to step onto and use for assistance in pull-ups, muscles ups, dips, levers and more! You can get creative with these bands and use them for assistance in almost any exercise. I've even seen folks use them for assistance in planche progressions.
