I love body weight exercises, so I thought I would throw up a quick workout you can do at home with no equipment.
Do 15 reps of each exercise, then immediately move to the next. Repeat the cycle as many times as you can, or for a time limit (for example, 30 min).
Single Leg RDL
Vertical Pushup (or half vertical, with feet on a chair or bed)
One thing to note on this workout, is that it does not include any back or bicep exercises. There are body weight exercises for these area, but they typically require equipment such as a pull up bar or TRX. I am sure there are things you can do without equipment for your back, but I doubt they are as effective or they require more experience than the average person has. That said, this can be a great workout for vacation or times you can’t make it to the gym, just don’t make it a long term routine.
