Keeping a consistent workout routine is easy once it becomes a habitual part of your daily routine. However, that faithful routine can easily slip when you're thrown out of your regular routine, whether it be due to travel, time off, limited gym access, etc. When access to equipment is limited, it's still possible to get a great workout in with just the use of dumbbells. Below is a full lower body workout that can be done with nothing other than dumbbells and a bench (or other elevated surface).
Exercise 1: Dumbbell Deadlift
Place a set of dumbbells on the floor in front of you. Stand with your feet about hip width apart. Squat down to grab the bar with your arms just on the outside of your knees. Drive through your heels to stand up with the bar, squeezing your glutes and lightly locking the knees at the top of the motion. Rather than using your back to pull the bar up, imagine pushing your feet into the floor and using your legs to bring the bar up. Keep a straight back, a neutral head and neck (chin slightly tucked) and engage the core. Make sure the dumbbells stay as close to your legs as possible throughout the entire range of motion. Lower the bar back to the ground with control, the same way you lifted it to complete one rep.
Perform 3-4 sets.
