1-10 minute microburst workouts throughout the day and week can lead to improved cardiorespiratory fitness, strength and mobility. Your fitness level and health history dictate what exercises are safe so be sure to assess the quality of your movement when trying exercises out. Use a wall for 1 min posture exercises like snow angels or wall slides, use a counter top, wall or floor for a quick set of push-ups. Single leg balance work with arm movements or knee lifts or hinging take a minute and are superior to just standing on one leg. Investing in a few bands or tubing you can pull on to improve upper back strength is important to offset presses and push-ups. SPRI handled tubing with a door strap is a great investment!
No . . . no . . . and no!! There are so many ways to great workout without walking away drench (though that does feel great on days you have time to shower lol)
I love strength training workouts because I sweat WAY less then when I do Cardio. Other great options . . . 20-30 minutes of booty and core! Those are my absolute favorite, they pack a punch and I can look "fresh" pretty quickly after completing them.
