Ok. You can do a full body workout that comprise compound exercises that will target your legs and arms.
You can do this 4 sets of exercises with a 30 seconds rest in between sets. That’s with your normal warm up routine then post workout cooldown and stretches.
Squat (body weight) of 3 sets: 10 reps then straight to
Push ups 3 sets: 10 reps then rest for 30 seconds. (Go on your knee)
Standing overhead press with dumbbells of 3 sets: 10 reps then straight to farmers walk of a total of 20 steps. Maybe do 10 steps then you turn and do another 10 steps so your back to your station. So also do that for three sets with having 30 seconds in between sets.
Light barbell row of 3 sets: 10 reps then plank for 40 seconds. Then have a 30 seconds rest.
Now the total exercises should be done between 15-20 minutes. You are working all your whole body to keep it balanced which much emphasis on the legs and arms. It’s fairly intense if you do the set times so you get a great cardio workout as well.
If your not sure of the forms you can go to YouTube and look at “Howcast” people. They give a detailed information on how to perform the exercise.
I hope that helps.
