Home Workouts During Mandatory Lockdowns & Quarantines

For who? Baby Boomers, retirees, competitive athletes, work-at-home employees, study-at-home students
For what? Strength, stamina, functional movement, mobility, flexibility, warm-up, recovery, KAATSU Cycle









As schools, universities, cities, organizations and governments close in unprecedented numbers around the globe due to the coronavirus pandemic and fears about infection from COVID-19, some individuals find themselves limited to their homes and neighborhoods.

While precautions are prudent and wisely followed, people still need to work and eat, and many want to rehabilitate and exercise as usual.

Telecommuting enables people to work from home together with their far-flung co-workers. Eating is certainly not an issue (if local residents are not stockpiling food and water), but rehabilitating and exercise can be more problematic for many people.

A walk outside, a jog around a local park, bodyweight exercises or yoga indoors can be done during temporary lockdowns and mandatory telecommuting policies set by corporations or governments. But going to a physical therapy clinic for rehabilitation or heading to a fitness gym that is located further away may not be a conveniently easy option.

This is where the KAATSU Cycle 2.0 can help.

The KAATSU Cycle 2.0 is compact (handheld) and can be done anywhere anytime by anyone doing anything. From stretching and doing therapeutic movements to walking upstairs and doing push-ups with the KAATSU Cycle 2.0 is effective and efficient. Even the standard KAATSU 3-Point Exercises on your arms or legs [shown above] are tremendously beneficial and provide a great stress relief in these times of the unknown.

In times of stress, especially while being forced to limit outdoor activities and travel, simple leg and easy-to-do core exercises with KAATSU equipment are a great way to stay fit and not gain weight.

KAATSU Walking can provide the same effect as significantly longer (in duration and distance) runs, jogs and walks. Simply put the KAATSU Air Bands on your legs and walk in or around your home or stretch [see photo on left].

Advanced KAATSU 3-Point Exercises for the legs (i.e., Standing Heel Raises, Leg Curls, and Quarter Squats) are a great finisher to the KAATSU Walking.

The KAATSU Air Bands on your upper legs will result in healthful systemic effects that are felt and seen throughout your body, including your core and upper body.

But if you want to focus on your core, you do not have to do planks, crunches and other forms of abdominal work. Instead, KAATSU users can do a number of simple KAATSU exercises to strengthen their lower back and tighten their core.

Core and lower back exercises can comprise of your entire KAATSU training session for the day. Alternatively, core and lower back exercises can be an addition to your typical KAATSU sessions.
