Doing just four simple exercises can be a great way to tone your whole body. First, split squats. Do 10 repetitions and the switch. Pushups. If you can’t go all the way to the floor, do them against a chair. Do as many as you can in 40 seconds. It’s time for your back and biceps. Do 10-15 pulldowns. Finish this first session with triceps dips for 40 seconds. Repeat the entire session four times.
