If I could only choose four exercises to perform daily, the squat, the push up, the plank and the pull up would be the ones I would pick.
Here is why:
Squats: Squats are a great full-body exercise that strengthen the muscles in your legs, glutes, core, and back. Doing squats daily helps to improve your overall strength and balance and can help to prevent injury.
Push-ups: Push-ups are a great upper body exercise that strengthens the muscles in your chest, shoulders, arms, and core. Doing push-ups daily helps to improve your upper body strength and posture and can help to prevent injury.
